Chelsea midfielder John Obi Mikel has revealed Carlo Ancelotti read his side the riot act during half-time of their FA Cup win over Cardiff.
The Blues went in level at 1-1 at the break at Stamford Bridge before running out comfortable 4-1 winners to book their place in the quarter-finals.
Ancelotti was not happy with Chelsea's first half performance against Cardiff and Nigerian ace Mikel admits the Italian went "crazy" with the players.
"When we went back into the dressing room today the manager was crazy, so we went into the second half knowing what we had to do," said Mikel.
"He went mad at us. He shouted at us in English and Italian - everything. When he's mad he mixes everything up.
"We knew we could do better. But we came out in the second half and that's what we gave him."
Mikel also admitted Chelsea need to improve their away form if they want to maintain their push for glory on three fronts.
Chelsea remain unbeaten at home this season, but have just one win in their last six games away from Stamford Bridge.
Mikel knows their away form has to improve and he is confident they can get results on their travels.
"Our away form is something that we need to sort out," added Mikel.
"We need to speak about it, but we know what we can do. We know what our players are capable of.
"If you look at us, we have some big players in this team, and when things are not going well, we know how to sort things out and put things right.
"We have got a very good manager, a very experienced manager who is going to put things right for us. We have to try and win all our games from now on."
