Arsenal coach Arsene Wenger says he is ready to put an end to his 12-game winless run against Chelsea coach Jose Mourinho when the Premier League leader visits the EmiratesStadium on Sunday in a top-of-the-table Premier League clash. Chelsea is 10 points clear of second-placed Arsenal with six games remaining this season but Wenger’s team will be confident afterhis side’s run of nine straight wins in all competitions. “I’m not a great believer in history,” Wenger said. “I just think football is down to the fact that the performance on the daywill decide the game and the result, so let’s focus on that.”
