Last month, a 90th-minute tally enabled Timao to walk away from the Maracana with a 2-2 draw in the first leg as they look to advance beyond this stage of the competition for the first time since 2018.
Match preview
Another resilient comeback for Corinthians at the end of August has them in an ideal position to make the final of this competition.
Coming from behind has been among the big stories for this side throughout the majority of the 2022 Copa do Brasil.
Vitor Pereira saw his side draw Portuguesa RJ 1-1 in their opening Third Round affair before reversing a 2-0 deficit in the Quarter-Finals by beating Atletico Goianiense 4-1 in the return fixture and then twice coming back from one-goal deficits against Flu just over two weeks ago.
While their track record suggests this team will be in for another close game on Thursday, Corinthians will fancy their chances to advance given their home form.
They have only lost twice at Corinthians Arena in all competitions since February, with those defeats coming against Flamengo and Palmeiras.
Timao hold a 100% record at home in this competition, outscoring their opponents 10-1 in those three matches, while winning four of their previous five games at home to Fluminense, failing to concede a goal against them in back-to-back encounters.
Corinthians are one of Brazil's most well-organised and compact defensive units, currently tied for third when it comes to goals conceded in the current Campeonato Brasileiro Serie A campaign (25).
In seven previous appearances at the Semi-Final of this competition, the club from the Tatuape district of Sao Paulo have only been eliminated once, back in 1997.
Making their first Semi-Final appearance at this competition since 2015, Fluminense started the opening leg brightly, earning a penalty and taking the lead after four minutes, ending the game with 65% of the possession, holding the visitors to just two shots on target.
The bad news is that they conceded on both of those efforts, and now they will have to do something they have not managed to do since late July in any competition, win away from home.
It is by no means a lost cause for them however as they hold a 100% road record in the Copa do Brasil this year, winning all three of their away matches by a combined score of 6-0.
Flu have triumphed in every match at this competition when scoring the opening goal, though they have only been able to do that once in their previous three domestic fixtures, defeating Fortaleza 2-1 last weekend.
Their opponents on Thursday may have one of the best defences in the Brasileiro Serie A, but Fernando Diniz's men can boast one of the best attacks in the top-flight, scoring the third-most goals to this point of the domestic campaign (40).
Tricolor have not advanced beyond this stage of the Copa do Brasil since 2007, when they lifted the trophy for the first and only time to date, losing on penalties in the 2015 Semi-Final versus Palmeiras.

Fluminense possible starting lineup:
Fabio; S. Xavier, Nino, Manoel, Paulista; Andre, Nathan; Martinelli, Ganso, Arias; Cano
We say: Corinthians 1-1 Fluminense (Corinthians advances on penalties)
The deciding match of this tie will be a challenging game to call seeing one team is sharp in the attack, while the other is stingy along the backline.
We are giving the home side a slight edge because of their impressive form at Corinthians Arena, though in reality this match could go either way.
