Jose Mourinho: Chelsea boss appears to criticise Arsene Wenger

Chelsea boss Jose Mourinho appears to criticise Arsenal boss Arsenal Wenger during his news conference for Saturday's game with Newcastle.

Mourinho also refuses to answer questions about Diego Costa in light of the Chelsea striker's three-game ban for violent conduct during last weekend's 2-0 win over Arsenal.

Mourinho and Wenger have had a long-running rivalry, with Mourinho famously calling Wenger a "specialist in failure".
