Chelsea head coach Guus Hiddink admitted that he lost his temper with his side at half-time of their thrilling 4-4 Champions League draw at home to Liverpool.
The Blues were 2-0 down after 45 minutes at Stamford Bridge leaving the quarter-final tie delicately poised at 3-3, before Chelsea hit back to lead 3-2 on the night.
However, Liverpool set up an absorbing finale by scoring twice late on to make the aggregate scoreline 6-5 to the Blues, before Frank Lampard's last-minute strike confirmed Chelsea's passage to the last four.
Dutchman Hiddink revealed afterwards: "We talked to them, my colleagues talked to them and sometimes you lose a bit of your temper. But they reacted and they also knew the first half was not okay.
"But if you give a team like Liverpool too much space then you are in trouble.
"We were angry because we didn't start as we planned and we know Liverpool are a good team tactically, with very skilful players.
"You cannot give them a lot of space but we did. We dropped back too much and looked for safety.
"The focus was also on the duels. We lost too many of them in the first half and that was not good.
"Tactically, but also mentally, we said to each other, that it was not the way we would start the second half. That's why I like to work with this team, it reacts.
"We knew that we could score and happily we did rather early after the beginning of the second half. But you cannot stay angry because then the anger becomes frustration.
"But this was one of those games where players have made a lot of errors. That's why it was very attractive - going from one goal to the other.
"It was very dramatic. One moment you think you are down and then the team reacts and then you are up, before you are down again. It was a wave of being in the game then almost being out of it.
"It is exciting, but you suffer a lot when you are responsible. When it is paying off as it did tonight it is good to be involved for many, many years."
