Throughout the season former player Clive Walker provides radio and TV commentary on Chelsea's games. Here he selects five aspects from Sunday's recovery and victory on Merseyside that caught his eye…

1. Going to Everton in all the time I can remember has been tough, and most professionals will tell you the same, as do Chelsea's results there in the past. So to go there and get the win is something to be very pleased about.It was like tactical warfare between the two managers at the start, trying to surprise each other with changed formations and then making little tweaks to try to counter the other. Chelsea started with a 4-3-3 and Everton had Victor Anichebe on the left and Steven Pienaar in the centre and initially we struggled as they came out the blocks with great desire and had people giving us problems.

2. Everton's main thrust is all about team ethic and work rate and they do what they do well. On a good day they get the ball into the box and Anichebe in the first 20 minutes gave Cesar Azpilicueta a hard time physically. It was also a learning curve for our young right-back playing at Everton and he didn't look as comfortable as the player we have seen of late. Ramires chosen on that same flank was a lot to do with tying down Leighton Baines and I can understand that away from home, although there were a couple of occasions in that first half when Ramires picked the ball up a lot deeper and ran and that is when he looked a really asset.

3. Whatever the formation, you have to get at the opposition team and with half an hour gone Chelsea could have been dead and buried, but Nikica Jelavic is not scoring at the rate he was last season and Anichebe has never been prolific, which leaves it to Steven Pienaar and Leon Osman to score goals. At 1-0 you thought Everton might push on but it never happened. At some stage we knew there would be a period when we were on top and fortunately that came with 10 to 15 minutes to go in the first half. We weathered a storm that should have burst the dam but it didn't and teams can't get away with that against big sides, you have to bury them when you are on top. We managed to claw ourselves back in to the game by half time.

4. On the face of it, it might be considered a surprise Everton left such space for Frank Lampard to score his first goal, but he has done that all his career - found space. It was a very good finish. Heading back where the ball came from was out of the text book and it gave Tim Howard no chance. Everton were slow in closing Ramires down and that gave him the chance to put the ball in the box. On the half turn he didn't look up but just used his left foot to put it back in the mix and sometimes that is all you have time to do.

5. Chelsea had seven or eight players in the second half playing really well and there was some classic movement that led to the winning goal. Mata had begun to get on the ball in the 15 minutes before half time and it was a lovely pass by him over the top to Hazard. Fernando Torres too was getting better delivery in to him but he was up against Sylvain Distin who had a terrific game.
