Chelsea coach Thomas Tuchel said his side were closing the gap with Manchester City and their "benchmark" coach Pep Guardiola after the Londoners' 1-0 FA Cup semi-final win on Saturday.
The victory for the Blues -- Tuchel's first over Guardiola -- contrasted with a 3-1 drubbing in the home by City in early January, which hastened the departure of former Chelsea boss Frank Lampard and his replacement by Tuchel.
"In the event that you play against Pep, you understand that you play against the best level in Europe because everywhere where he was on the sidelines, with Barcelona, Bayern Munich and now Manchester City, he was the benchmark for years with his teams and he's again," Tuchel said.
"Our target is to close the gap for the 90 minutes because it's possible in football and if you arrive in a good momentum, you can create this happen," he said.
"I am very, very happy and proud of the performance of we because we used a whole lot of courage."
Saturday's win -- secured with a 55th-minute goal by Morocco forward Hakim Ziyech -- leaves Chelsea in the search for silverware in the May 15 FA Cup final against either Leicester City or Southampton, and in the Champions League with a semi-final clash looming against Real Madrid.
Tuchel said beating Manchester City would supply the young players in his squad a confidence boost but he reminded them that they now faced a "crucial week" in the Premier League.
Chelsea host Brighton on Tuesday and travel next Saturday to West Ham United who are locked in a battle with the Blues for a top-four finish.
Guardiola congratulated Chelsea for their win but said the match could have gone in any event.
"It was a good game. Anything could happen," he said.
The Spaniard bristled when asked by a reporter whether his decision to make eight changes from the medial side which beat Borussia Dortmund in the Champions League midweek had contributed to the defeat.
"I am delighted using what we have done so far. The amount of games we have played... and all the players make absolutely everything," he said. "Do you think we don't pay attention in the overall game?"
