A 3-0 win over Leicester didn’t stop the German from pacing his technical zone or barking orders at his league leaders.
Goals from Toni Rudiger, N’Golo Kante and substitute Christian Pulisic secured a dominant victory for Chelsea – but Tuchel has revealed why he is still worried.
He insisted his players should have killed Brendan Rodgers’ side earlier – having to wait for Pulisic to leave the bench to add a third in the 71st minute.
The Chelsea manager said: “You have to decide the game when it is possible to decide it. I thought we could be more precise, we could be more clinical in the last third of the first half because we played with such an effort, we had such good ball recoveries at the top of the field, we were good for finding spaces with the ball high up the pitch and we all know that a third goal would have decided the game.
“With a two-goal lead, you can never be comfortable because a goal, a free kick, a deflected shot can change the momentum and suddenly you’re fighting when you don’t have to.”
Tuchel added: “I am happy, but there is always so much room for improvement. The players got all their praise after the game and they know very well when they are having a good game and when they have had a good game.
“It’s a team effort and it’s a huge effort that we put in to attack and defend and I’m happy the team got the win they deserved.”
The victory was another title declaration for Chelsea – keeping them ahead of rivals Manchester City and Liverpool.
But Tuchel wants more, saying: “There are still things to improve – technical errors in the final third, decision making and conversion of chances.
“But it was a very good performance, a tough performance, a mature performance. We needed it to have a deserved win and a clean sheet. We’re happy.”
