Proudly donning his "Striver" t-shirt - an app developed by himself and compatriot Roberto Carlos with the aim of becoming the world's first abuse-free social media platform - Gilberto's ambition to quash harmful stereotypes around what it means to be a man has seen the Premier League title winner link up with CALM (Campaign Against Living Miserably) as their latest high-profile ambassador.
A plethora of esteemed celebrities in and outside the world of sport have already pledged their support to help CALM deliver their paramount message; Declan Rice, Fran Kirby, Ricky Hatton and Joe Marler are among those welcoming Gilberto into the ambassadors' circle, which also includes the likes of comedian Romesh Ranganathan and musical artist Professor Green.
In the wake of significant physical and psychological devastation stemming from the coronavirus pandemic - which saw rates of anxiety and depression shoot up by 25% in the first year of lockdowns, according to figures from the World Health Organisation - the hourly headlines now frequently display the untold horror of war and an endless conveyor belt of stories surrounding the disconcerting climate and cost-of-living crises.
Such harrowing scenes may lead someone to believe that there is little hope for the future, which is where CALM endeavours to step in. With ONS figures showing that 125 people die from suicide - the biggest killer in men under 50 - each week in the UK, Gilberto is committed to ending the "men don't cry" cliche and encouraging everyone to extend an arm out for support.
"I heard about CALM a few years ago and started to understand the work they are doing in society. There are still some people who don't know exactly what they are doing. [I want] to give them the best support as I can but also to help them spread their message and what they're doing to help people," Gilberto told Sports Mole.
"Especially men, we are a little bit concerned about who we ask for help and where we go for it. As long as we get the support we need when it's necessary. As men we grew up, watched some movies maybe believing we are superheroes, we cannot cry, believe that we are unbreakable. We just need to find a way to live peacefully, but when we need help just ask for it, and joining CALM is to help them deliver their good message. I'm very happy, so motivated to give my best in this project."
One man who knows all too well about fronting up in the face of adversity, Gilberto grew up in poverty in Brazil before his big break in football, which saw the 47-year-old retire with 12 major honours to his name from his exploits in the colours of Arsenal, Brazil, America Mineiro, Atletico Mineiro, Gremio and Panathinaikos.
An unsung hero of Arsene Wenger's iconic 4-4-2 system - at a time when Arsenal were public enemy number one in the Premier League - Gilberto's midfield partnership with Patrick Vieira was fundamental in propelling Arsenal to 2003-04 Premier League glory, allowing him to proudly don his "Invincibles" badge wherever he goes.
World Cup, Copa America and Confederations Cup supremacy was also ticked off Gilberto's checklist, and alongside his haul of individual and team accolades, the South American pocketed wages which the average Joe can only fantasise about. However, Gilberto does not equate money with happiness, as even the most talented athletes are no less vulnerable to psychological hardship.
Mental health has already been a hot-button topic in the embryonic stages of the 2023-24 Premier League season, with Tottenham Hotspur attacker Richarlison openly admitting to seeking help after cutting an inconsolable figure while playing for Brazil. Offering his full support to Richarlison, Spurs boss Ange Postecoglou insisted that no amount of zeros on a paycheck will make a player "immune from life itself".
In addition, Burnley recently revealed that striker Lyle Foster would be taking an indefinite break from football to receive treatment for a mental health issue, and Gilberto can understand how off-field traumas coupled with the burden of delivering on the pitch can push a seasoned professional to breaking point, especially with modern social media awash with vitriol.
"I think there is confusion about being successful, having money, with mental issues you may have. It can be from trauma or a problem you had in the past - somebody from your family or a relationship or big disappointment in life. Something you never have healed from," the 47-year-old added. "And then you have to deal with the pressure of the game, and the judgement of people when you don't do well. People get so impatient, they criticise you.
"Criticism is OK, it's part of if you play well or not. You can have your opinion - what I disagree with towards sportspeople is when they lose, make a mistake or don't do well, they can abused, especially on social media. This has crossed the line between what is criticism and what is abusive. This can start to generate anxiety in players, who are not going to talk to the media or look at their social media."
Of course, there was no TikTok, Instagram, Twitter - or X - during Gilberto's playing heyday; the Nokia 3210 and Motorola flip phones were the rage back then. While the absence of such platforms did not make sportspeople exempt from criticism in the papers, lax regulations on the most prominent social media websites allow 'fans' to bombard players with incessant abuse from the safety of their keyboard at any opportunity.
Too often we witness players deactivating their social media accounts after a poor display on the field, either as a pre-emptive measure or in the wake of despicable hate messages; Bukayo Saka conceded that he "instantly" knew of the abhorrent comments he, Jadon Sancho and Marcus Rashford would be subjected to after missing from the spot in the Euro 2020 final. While urging social media platforms to do more to tackle online abuse from "miserable" people, Gilberto has implored his fellow professionals to block out the "stupid" comments and focus on the supporters who stick with their beloved team through thick and thin.
"Players, don't pay attention to social media. Don't listen to these stupid comments. These people who abuse you, are they a real fan of your club? If you put your attention on the bad comments, you forget the other good people who support you," Gilberto said. "Fans have to be the external support the players have when things does not go right. Instead, they come to their social media and trawl through a lot of abusive comments on them.
"This problem, it's not exactly social media in my opinion, but people's behaviour on social media. The clubs have to give support but the social media platforms also have to give support people who get abused, to tackle this big problem. You are miserable attacking somebody, you are not a better person attacking somebody because they didn't do well."
A fellow CALM ambassador who has been basking in adulation from the Emirates faithful for a few months now, former West Ham United skipper Rice - and the Arsenal powers-that-be - risked the wrath of Gooners if his record-breaking £105m Emirates arrival failed to bear fruit immediately. Living up to the pressure of a nine-figure price tag - and being the most expensive British footballer in history - has sometimes been a weight too heavy for Jack Grealish to carry amid his indifferent form at Manchester City, but Rice has arguably already justified Arsenal's bank-breaking decision.
Already establishing a reputation as one of the division's best ball-winners and a driving midfield force while in the claret colours of West Ham United, Rice has seamlessly slotted into the Arsenal XI - either as a number six or number eight - and came up with crucial goals against Manchester United and Chelsea before Tuesday's astounding last-gasp winner versus Luton Town to extend the Gunners' lead at the top of the Premier League table.
Mikel Arteta's lust to increase Rice's attacking output is paying major dividends - only Rodri (131) has made more passes into the final third than the England international's 112 in the Premier League this season, while he also ranks in the top 10 for progressive passes with 104. However, Rice has not abandoned the magnificent holding qualities which made him a major coup in the first place; 23 interceptions this season is only bettered by Fulham's Antonee Robinson with 38.
"I'm so happy to see Declan at Arsenal, the way he's been playing and I'm happy to see that he's also a CALM ambassador. I hope he keeps doing well, he's been amazing since he came to the club," Gilberto said of the £105m man. "He understands what Mikel wants, it was so easy for him to adapt, I hope he keeps that up, because consistency in his position is so important. He has been consistent since he arrived, which is important because he's been fit, he's made a huge difference and he improves other players. This position, you can sometimes be unseen on the field, I know how that is! But you are the position where you give the balance between the attacking players and the defenders. He knows how to manage himself, he's brilliant."
Despite Rice's frequent deployment as a number eight, Gilberto believes that the Englishman is still a six at heart and has even claimed that his physicality and tackling is superior to that of Rodri - many people's pick for the best holding midfielder in the world right now - but the Manchester City man's football intelligence is what sets him apart from the rest, explaining: "I still think he is a number six. Most of the teams who won a lot of trophies, they have a pillar in that position. City have Rodri - I think in terms of physicality and tackling, Declan is better than him, but Rodri is very intelligent."
Rice touching down at the Emirates Stadium coincided with the departure of Granit Xhaka, a former Arsenal skipper who unexpectedly rebuilt burned bridges with the fanbase after his infamous Crystal Palace outburst of 2019, as Arteta convinced the Swiss enforcer to continue in red and white before he departed on the back of his most productive Premier League season for the Gunners.
