After a slow start, and then going a goal down, the Blues developed a sudden sense of belief.
Wheher it was down to Louis Saha's first goal or David Moyes' half-time team talk, I don't know. But there was a marked difference once Everton started getting at them and closing them down, preventing Chelsea from dictating the pace.
I thought there was a level of over-confidence with some of Chelsea's players and Everton made them pay for that.
It was an important win after losing in the derby. Similar to the first derby defeat of the season in November, I thought we deserved more at Anfield.
However, the players came out of the Goodison derby with their heads held high and went on a fantastic run in the league.
Who's to say they can't go on another good run now? It was a fantastic response against Chelsea. Hopefully that can act as a spur moving forward.
