Ashley Cole dropped by Jose Mourinho after attending Arsenal's Christmas party days before London derby Mourinho added: "I will play Branislav Ivanovic at right-back and Azpilicueta at left-back. From the beginning, Ashley is not playing, unless something happens between now and Monday. Normally, I'll play Azpilicueta at left-back. Victory for Chelsea will put them above Arsenal, the current leaders, and Mourinho goes into the game knowing he has never lost to Arsène Wenger. But he added: "It's not me against Wenger. It's my Chelsea against his Arsenal. That [statistic] doesn't play on Monday. It has no influence, it means nothing for Monday. He also denied having a psychological edge over Chelsea's London rivals. I just feel that we've played better, we deserved more, so we won those matches. In my time, I remember just one game where we were close to losing, a game at home where [Michael] Essien scored an equaliser in the last part of the game. Even at the Emirates, playing with 10 men for 75 minutes, we played a fantastic match and drew 1-1. My memories are that, against them, we play very good matches. As a consequence, we have got good results. After defeats against Stoke City and then Sunderland in the Capital One Cup, he said he has been working hard on making Chelsea harder to beat. He has conceded he does not have the firepower of the other leading sides, with no away goals from any of his three strikers - Fernando Torres, Demba Ba and Samuel Eto'o - in the league so far this season. "We know that we don't have the players with the qualities to be the killer who scores week after week, game after game," Mourinho said. But we can improve our results having more security when we lose possession. We are being punished when we lose the ball. One of the aspects we have to improve is the defensive work by the attacking players when the team loses the ball. We cannot let the players hide behind the fact we're not scoring enough goals. We work, as we did this morning. We only worked on defensive aspects of the game this morning.
