London, Aug 16 (IANS): English Premier League (EPL) club Chelsea head coach Jose Mourinho has taken a dig again at his Arsenal counterpart Arsene Wenger's win record.

Manchester City coach Manuel Pellegrini recently signed a new contract with the club after finishing behind champions Chelsea last season.

Asked if he was surprised by the contract given to Pellegrini, Mourinho on Saturday was quoted by bbc.com as saying: "Why? Some other clubs, they have disappointed for 15 years and the manager is the same."

London based football club Arsenal last won the EPL under Wenger in 2003-04. But the Frenchman has helped them win two back-to-back FA Cup titles in the last two seasons.

Wenger also triumphed over Mourinho two weeks back when Arsenal won the Community Shield in this season's curtain raiser.

There is a history of conflicts between the pair, with Mourinho claiming Wenger was "a specialist in failure" in February last year, while the Arsenal coach has previously accused his Chelsea counterpart of being "disrespectful".
