Wenger backs Carneiro

Arsenal manager Arsene Wenger said on Friday that Chelsea's first-team doctor had been clearly following the rules in the incident that has reportedly seen her demoted by manager Jose Mourinho.

British press reports claim Mourinho has sidelined Eva Carneiro and physiotherapist Jon Fearn from matches and training sessions after they angered him by running onto the pitch to treat Eden Hazard during the latter stages of Chelsea's 2-2 draw with Swansea City last weekend, temporarily reducing his team to nine players.

Mourinho has been strongly criticised over the reports and Wenger said that it was dangerous for a manager to do anything that might damage unity within his club.

"It is a problem inside the club that if you are not united, it is more difficult. It is the trust and unity that makes the strength," the Frenchman, a long-time Mourinho adversary, told a press conference.

"You know you speak about that story at Chelsea. First of all I have not followed that as you know I do not have great interest about what is going on at Chelsea.

"Secondly the rules are quite clear that when the referee gives an indication that the medical (staff) can come on, they come on.

"After that what happens specifically in the situation I don't know, but the rules are quite clear. It is the referee who makes the decision."
