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

It was a very professional performance on a day when West Ham let us play and Chelsea showed how good we can be. We learned a lesson from the game at Upton Park because their tactics were similar again, with long balls played forward, but we dealt with it better. We looked inventive and were not going to let the same thing happen to us again. If we had scored four or five goals it would have been no more than the performance deserved.

Because Chelsea started brightly it kept West Ham on the back foot and the only balls they could get out of trouble with were the long ones to Andy Carroll. David Luiz and Gary Cahill, and John Terry when he came on, coped with those pretty well and when one missed out the other centre-back picked up the bits and pieces.

Eden Hazard is absolutely flying at the moment and as with all players who are flair players, when they are in good form they stand out. Juan Mata has been the more consistent of the two this season but when they are both playing well they get the fans off their seats. Hazard against West Ham was good with close control in tight areas whereas Mata finds the space first and creates in that space. West Ham are a well-organised team but when players like those two are in form they will find a weakness and they gave Joey O'Brien, a right-back playing at left-back, big problems. It stretched the rest of their backline and while Hazard was the catalyst, Mata's passing was superb.

Demba Ba had a tough game in front of the target but with his back to goal he played a big part in the win. West Ham eventually took centre-back James Collins off which was a bit of a surprise but maybe he had an injury. James Tomkins came on and Ba did the same job on him. He missed those opportunities but team-wise, he enabled us to pick up the bits and pieces.

Frank Lampard is playing as one of the deeper midfielders these days but when the team is playing well, he can still play his natural game and as we saw on Sunday, his timing of his runs into the box remains fantastic. If you have players on the ball who have the amount of time to deliver that West Ham allowed, then the right balls are going to come in, like the one from Hazard for the opening goal. It is at times when the team are not playing so well that Lampard has to play a significantly different role
