Chelsea coach Jose Mourinho says his unbeaten record in 12 games against Arsenal coach Arsene Wenger is irrelevant ahead of the teams’ meeting in the Premier League on Sunday.”For me, achievement is to win (on Sunday),” he told reporters at his pre-game press conference on Friday. “It’s not the other 12 matches that we played before against Arsenal. It’s a big club withthe same objectives that we have in the competitions we play. Because of that always comes a little bit of rivalry. He’s not my rival. I just feel he’s the manager of a big club in the same city whereI work and I live.” Mourinho famously labeled Wenger “a specialist in failure” when asked about the Frenchman’s record last season.
