Chelsea strolled into the fourth round of the FA Cup after a 5-1 win over non-league Chesterfield.
The European champions swatted aside the National League leaders, with five different players finding the net.
Timo Werner opened the scoring with a tap-in before Callum Hudson-Odoi doubled the lead with a superb, curled effort.
Romelu Lukaku added a third from a couple of yards out before Andreas Christensen's header made it 4-0 before the break.
Hakim Ziyech made it 5-0 with a penalty after the interval. But Chesterfield pulled back a goal ten minutes from time when Akwasi Asante tapped in a consolation in front of a huge away following.
For Chelsea, it was the perfect warm-up ahead of what is set to be a big week for Chelsea. They travel to Tottenham on Wednesday looking to finish the job in their EFL Cup semi-final, before a huge Premier League game away at leaders Manchester City next Saturday.
Here are five talking points to emerge from tonight's Stamford Bridge tussle.
Respect from Tuchel
The German made alterations, as expected, but perhaps fielded a stronger starting XI than many expected.
Romelu Lukaku, Timo Werner, Christian Pulisic and Mateo Kovacic can all be considered first choices on their day and are all established international players. It shows how much Tuchel values this competition.
"It's always a strong line-up when you play for Chelsea," he said pre-match.
"We know we have to put in the work out there. It's on us to make it a not pleasant experience for them (Chesterfield)."
Even the bench was jam-packed with quality, containing the likes of Jorginho, Reuben Loftus-Cheek and Havertz.
Lukaku watch
A week is a long time in football. Last weekend saw the Belgian frozen out by Tuchel after his ill-advised comments about his situation at Chelsea.
A public making-up has since followed and after starting the midweek win over Tottenham, Lukaku was again thrown in from the start here.
He had an early sniff, firing over the bar from a well-worked corner routine. But once he had got his eye in there was no way he was going to miss, when he scored Chelsea's third from close range on 20 minutes.
His hold-up play, even against non-league defenders, was impressive as ever. His only disappointment might have been the fact he was hooked at half-time, before he got the chance to really fill his boots.
Lewis Hall stars
The 17-year-old became the youngest-ever player to start a game in the FA Cup for Chelsea.
Despite being employed on the left of a back three, Hall can play in a number of different positions and that versatility was evident in the first half. He was comfortable on the ball, and didn't need a second invitation to get forward.
He set up the third goal, showing great persistence to pester the Chesterfield defence into a mistake. Once he had won it back he immediately picked out Lukaku for a simple tap-in.
Another impressive trait for the youngster was his desire to ask for the ball in pressurised situations. On this performance, the future is bright for Hall.
Forgotten man returns
Lewis Baker has been at Chelsea since he was nine. He's now 26-years-old.
However, his appearance off the bench for the final half hour here was, quite amazingly, only a second-ever appearance for the club.
His first came in 2014, also off the bench in the FA Cup. Since then he has had ample loan spells away from Stamford Bridge.
In truth he has never come close to breaking into the first team and his contract is finally set to expire this summer.
This represented a poignant decision by Tuchel, with Baker knowing full well he will be leaving the club in a few months or perhaps before then if another loan opportunity presents itself before the window shuts.
Spireites far from disgraced
Chesterfield were the first away side to ever win at Stamford Bridge back in 1905.
Sadly for the 5,800 vocal fans who travelled down from Derbyshire, they never looked like repeating that feat.
A whopping 91 places separate the sides and for large portions it was clearly evident.
But when Asante tapped into the net from a few yards late on it represented a victory of sorts for the Spireites.
The thousands who had followed them down were making all the noise despite the goals flowing in against them, but Asante's goal was the least they deserved.
On a wider scale for Chesterfield, this was always a free hit and their main aim is a return to the EFL after a difficult few years on and off the pitch.
The money banked from this cup run will also help the club no end as they look to hold on to top spot in the National League.
