Chelsea diverted from our usual 3-4-3 formation and played with a four-man defence at Stamford Bridge, with Kai Havertz and Romelu Lukaku both leading the line.

Havertz was replaced at half-time by the returning Werner, who had missed the previous five games with Covid. He looked threatening once introduced at the interval, and followed up with a return to the scoresheet against Chesterfield on Saturday when he netted the opener inside six minutes.

When pressed on whether Timo’s return to form could prompt him to use both Lukaku and Werner up front together, Tuchel failed to dismiss the possibility.

‘We are Chelsea,' said Tuchel. 'We have our style, we have our positions, and we have enough possibilities. We can play with two strikers, we can play 5-3-2, we've played this many times with the ball and off the ball.

‘We have the same possibility to play with a formation with three strikers,’ Tuchel added. ‘Maybe even a 4-4-2, like in the match against Tottenham in the first leg, so we have some options.’

The Bavarian also challenged his players to make sure they prove a point once they take to the field, given the return of many key players in recent weeks and the competition for places within the squad.

‘The players need this, it is very easy. Players need to show they are good enough to step up. When they start, they need to show they should be on the pitch. It is very easy, we are not inventing new stuff to make players happy or better. They have all it takes. It is on them to show us.’
