Sunderland boss Steve Bruce says his players were given a "master class" by Chelsea in their 3-1 defeat to the Blues on Tuesday night.
Carlo Ancelotti's side came from behind for the second time in a week as Bruce suffered his first defeat as the Black Cats boss.
He told BBC Newcastle he could have no complaints with the outcome.
"Sometimes you just have to hold you hands up and admit you were beaten by an excellent team," he said.
"That's as good a Chelsea performance as I've witnessed in my time in the Premier League.
"The good thing for me is that we were gallant, we never gave it up - but that wasn't good enough."
Sunderland led at half time through Darren Bent's second goal in two games for the club, and Bruce admitted there were a number of positives elements in the game, despite the result.
"There are a lot of positives I can take from it," he said.
"It was a great education for Jordan Henderson to play against Ashley Cole and I thought you could see why Lorik Cana captained Marseille.
"The disappointing thing for me is that we've conceded the first goal from a corner. For all of Chelsea's great play, to concede from a corner is poor stuff from us."
Bruce also confirmed he has injury concerns over midfield duo Lee Cattermole and Lorik Cana after both picked up knocks in Tuesday night's game.
He said: "Lorik Cana is going to be having x-rays - he could have broken hand, he fell on it just before half time, so we'll see how that is.
"And Lee Cattermole has hurt his back."
