Paul Lambert admitted his side were "beaten up" by Chelsea - but backed his players to come roaring back to their best against Tottenham.
Lambert accepted his team were "second best" to the Champions League winners in all departments and could even have lost by more than the eight goals scored.
But the boss stressed that there was no point mulling over the heavy loss at Stamford Bridge with a big game against Andre Villas-Boas's men coming up thick and fast on Boxing Day.
He said: "Everything that could go wrong went wrong.
"We have been on a really good run but we got beaten up today by a really good side. We were second best.
"We never turned up. We have been beaten pretty heavily. But we were second best all over.
"Their first goal went in early. But even so you've still got 80-odd minutes to go.
"Then the second goes in and then the third and then you think 'get to half-time to give yourself some kind of respite.'
"In the second half it could have been more to be perfectly honest. All credit to Chelsea, they beat us up today.
"You always learn when you win, lose or draw. That will be a wake-up call for us, that.
"Things have been going really fine for us. It was only Man Utd, Man City and Chelsea now who have turned us over. We will bounce back!
"We only have two days to mull over it but we have to go again against Tottenham on Wednesday.
"I am sure whoever plays on Wednesday will atone for that."
Lambert said there was no point throwing teacups in the dressing room because the players were more than aware of their deficiencies on the day.
He added: "They know. You can go in there and rant and rave all you want but it won't really do you much good. They know my feelings on it.
"But they know themselves that they have let everybody down.
"Now we focus on Tottenham. It's never easy to turn up and win a game.
"But you can't let one game blight what has happened of late. We will certainly try to bounce back as quickly as we can."
Make sure you snap up your half season tickets.
