"If you play against Pep you know that you play against the highest level of Europe because wherever he was at the sideline – Barcelona, Bayern (Munich) and now Man City – for years he was the benchmark with his teams," Tuchel said.

"And he is again. You can see that with the Premier League.

"Our target was to close the gap for the 90 minutes because it's possible in football and if you arrive in good momentum, we can make this happen.

"I am very, very happy and proud with the performance of our team because we played with a lot of courage, we were very self-confident and played very brave with the ball and against the ball.

"We had a very good start to the match, the first 35 minutes of the first half and the first half of the second half.

"We deserved the win, which is most important. We were very active, we did not get passive and we deserved the win against, like I said, maybe the best manager and clearly one of the best teams.

"We are very happy with the performance and it will be a huge boost for our self-confidence and for our progression for our development because we arrived also with a young team and young players.

"It's important to have these experiences together and the most important now is to enjoy it today, let the players feel it.

"From today, it's the past and we need to perform in a crucial week in the Premier League."

Chelsea return to Wembley on May 15 and City will be back at the national stadium next weekend for the Carabao Cup final against Tottenham.

A midweek match against Aston Villa comes first after their hopes of winning an unprecedented quadruple came to an end on Saturday evening.

"The first half we struggled for 15 to 20 minutes, and the rest we didn't find the key players in the positions, in the pockets and we struggled a little bit for that," City boss Guardiola said.

"When we arrived there sometimes we didn't create much, but in the last minutes was much, much better.

"I try to avoid all the people (talking) about the four and always I said the same – 'the next one, next one'.

"I don't know what's going to happen this season. I'm incredibly delighted with what we have done so far because the amount of games we played.

"We didn't have a midweek in an eternity, and all the players make absolutely everything.

"Now it's like I said in the last month. So what is next? It's Aston Villa.

"Going there we need 10 points (to win the league) and you have to go to the first three and arrive good the next week the final the Carabao Cup and the Champions League semi-final against Paris St Germain."

The fixture schedule is relentless for City, who now face being without Kevin De Bruyne for part – or perhaps more – of it.

The playmaker went off in the 48th minute with what appeared to be an ankle injury.

"I don't know," Guardiola, who bristled when asked about eight changes, said. "He has pain now.

"They tell me tomorrow they're going to make a test with the doctors. Apparently it doesn't look quite good but we will see tomorrow."
