LONDON (AFP) - Chelsea manager Jose Mourinho refused to speak to the media after being sent to the stands during his side's 2-1 defeat at West Ham United on Saturday.

Mourinho was banished from the touchline at half-time by referee Jon Moss after Mauro Zarate had put West Ham 1-0 up and Chelsea midfielder Nemanja Matic had been sent off for two bookable offences, while Cesc Fabregas had seen a goal ruled out for a narrow offside.

With Mourinho watching on from the Upton Park directors' box, Gary Cahill equalised for Chelsea, only for Andy Carroll to head in a late winner that left the floundering Premier League champions 15th in the table.

Mourinho may now face a one-game stadium ban, having been handed a suspended ban by the Football Association last week for criticising the referee following his side's recent 3-1 home defeat by Southampton.

Chelsea, for whom Kurt Zouma had a header blocked right on the goal-line in the first half, could also be fined for failing to put anyone forward for the post-match press conference.

But goal-scorer Cahill did speak to the media, telling the BBC his team-mates were "devastated" by the defeat, which was Chelsea's fifth in 10 league games.

"In the first half the Cesc Fabregas goal could have been given and we had the goal that was nearly over the line. That sums up the way we're going," said the England centre-back.

"And then we've got the sending-off. Originally we played on - we thought the referee had played on. Maybe the assistant called it back. I'm not sure sure what's happened there.

"We've not had the rub of the green, but we're not feeling sorry for ourselves. We have to work hard to turn this around."

Chelsea assistant coach Silvino Louro was also sent to the stands by Moss for protesting about Matic's dismissal, while Fabregas and Diego Costa were booked for dissent.
