Chelsea won 1-0 last night against Spurs.
The Blues were dominant in the game and played a virtually flawless first half.
However, their problems hit in the second half and in the final third. The Blues eventually won 1-0 but Tuchel expected more from Chelsea.
“Every experience we make is a step forward if we are opening to learning from it,” he told BT Sport. “The whole first half we totally controlled the game, very high up the pitch. Maybe we lost confidence in the second half because we lost the ball possession. We never lost the belief or structure. If it is necessary to suffer, you have to suffer.
“A bit more killer instinct and aggressive in the box, it would have been nice to decide and there were chances we lacked a bit of determination in the box. It was a big win in an away game and I am very happy.
“It is not only about tactics, about how we play and live it. They lived it 100% with full power and intensity. We never lost the belief, faith or courage to push high and for that you have to be brave and we were and the winners in the end.”
