Mourinho Could Face FA Action   (Sky Sports)

Chelsea manager Jose Mourinho could face further Football Association sanctions after being sent to the stands during his side’s defeat at West Ham on Saturday.

The Premier League champions' poor start to the new season continued at Upton Park, with a 2-1 loss condemning them to their fifth defeat of the campaign. It is their worst ever start in the Premier League.

Mourinho was banished from the touchlines at half-time following a first half which had Chelsea midfielder Nemanja Matic shown a red card for two bookable offences and Cesc Fabregas having a goal ruled out for offside.

Earlier this month, Mourinho was fined £50,000 and given a suspended stadium ban for criticising referee Robert Madley following his side's 3-1 home loss to Southampton on October 3.

If he is deemed to have brought the game into disrepute then the FA is likely to take action.

The Portuguese coach declined to speak to the media after defeat in east London which left Chelsea languishing in 15th place, with 11 points from their opening 10 matches.

Chelsea owner Roman Abramovich has overseen 10 managerial changes during his 12 years in charge at Stamford Bridge. Mourinho remains the longest serving manager during the Abramovich-era, with his first stint at the club lasting just over three seasons.

Chelsea assistant coach Silvino Louro was also sent to the stands before half-time after remonstrating with the fourth official following Matic's sending off.

The Blues will face an automatic FA fine after receiving seven yellow cards during the loss to the Hammers, while they will be punished by the Premier League following Mourinho's failure to fulfil his post-match media requirements.

Gary Cahill cancelled out Mauro Zarate's opener early in the second half to give 10-man Chelsea hope of claiming a point, however Andy Carroll's late header ensured West Ham secured all three points.

While Mourinho and his coaches did not provide post-match comments to the media, Cahill did speak and told Sky Sports News HQ: said: "We're frustrated and it's just the way the season's going at the moment.

"That's the way our luck's going at the moment. But we're not feeling sorry for ourselves. And we'll just have to work harder to turn things around."

West Ham boss Slaven Bilic admitted he sympathised with Mourinho and said: "I feel for him. Decisions from his point of view have gone against him. I would moan if it was against us. But they are not mistakes, they are matters of opinion."
