CHELSEA V WEST

           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.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.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.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
