Jose Mourinho sent to the stands at West Ham but why was the Chelsea boss sent off?

Lots of speculation surrounding the incident after Mourinho failed to appear on the touchline for the second half

With Chelsea a goal down and a man down at Upton Park, manager Jose Mourinho failed to appear on the touchline for the second half of the match.

Instead, the Portuguese took up his place in the Directors Box at the ground, alongside assistant first-team coach Silvino Louro who had been sent off at the end of the first-half for bursting onto the pitch following Nemanja Matic's red card.

But why was Mourinho up there?

Immediately there was huge amounts of speculation surrounding the incident, with numerous stories coming out of Upton Park - all of them seemingly contradictory.

The pervading theory is that Mourinho was sent to the stands for attempting to get into referee Jonathan Moss' dressing room during half-time, an area that is off limits during the match.

No one appears to know for sure, we'll keep you updated once we know more.

Chelsea went a goal down in the first half after Mauro Zarate fired home after the ball was only half-cleared from a corner.

The Blues will certainly feel aggrieved after Cesc Fabregas was ruled offside when he looked just about on, while goal-line technology Hawk-Eye denied them a goal, correctly, by the smallest of margins.

Matic was then, deservedly, sent off for two clear yellow cards in a short space of time just before half-time.

Even though they were down to 10 men, Chelsea were much better in the second-half and eventually equalised through Gary Cahill, the centre-back bundling home from the corner.

However, substitute Andy Carroll but the home side back into the lead with a powerful header from an Aaron Cresswell cross with 15 minutes to go that gave West Ham all three points.

The Chelsea boss refused to speak to the media at the end of the match, instead leaving the stadium straight away and heading onto the team bus without even addressing his players.

Gary Cahill told Sky Sports after the match: "We don't feel sorry for ourselves, we can't. We'll work even harder to try and turn this around because it's a tough time at the minute."

After the game West Ham manager Slaven Bilic said: "I feel for Mourinho.

"A lot of decisions from his point of view have gone against him."
