West Ham 2-1 Chelsea: 5 things we learned as Mourinho and Matic see red in Upton Park meltdown

Super sub Andy Carroll inflicted a fifth defeat of the season on Chelsea after Jose Mourinho was sent off at half-time. The Chelsea boss was dismissed after an extraordinary first half which saw the reigning champions trail to a 17th-minute Mauro Zarate goal – and Nemanja Matic and assistant coach Silvino Louro sent off.

The Blues bench was furious that the Serbian midfielder was shown a second yellow just two minutes after Cesc Fabregas had a legitimate goal disallowed for offside. Louro was sent to the stands for protesting Matic's dismissal.

The Special One replaced the Spaniard with John Mikel at half-time before he watched the second half from the West Ham director's box. Gary Cahill lashed home a 56th-minute equaliser and a great rearguard effort seemed set to salvage the Blues a point.

But Carroll, who came on after 68 minutes, headed home the winner 10 minutes later for his first goal since January.

Here's what we learned:

1) Crisis far from over

Last weekend's win over Aston Villa and the midweek draw at Dinamo Kiev suggested the corner had been turned. Even after falling behind to an early goal and seeing Nemanja Matic sent off, they fought back bravely after the break and were 12 minutes from salvaging a point.

2) Andy Carroll is back

Slaven Bilic has lots of silky attacking options but the raw power of the England striker is still invaluable. Last week he came on to wreak havoc as West Ham scored two late goals to win at Crystal Palace. Against a dogged Chelsea defence, his back-post header earned another three points.

3) Payet outshining Hazard

The two played together for a season at Lille before the Belgian's £32m transfer to Chelsea. But last season's Player of the Year was again ineffective while the Frenchman dazzled down the West Ham left.

4) Chelsea struggling for top four

Chelsea are now not fighting for the title. They are struggling to reach the Champions League. Jose Mourinho's side lost three matches in winning the title last year. They have now lost five and could be 12 points behind Manchester City by tomorrow night.

5) West Ham love to hate Chelsea

John Terry's every touch was booed while Jose Mourinho was serenaded with: “You're getting sacked in the morning” followed by “You're not special anymore” before his half-time dismissal.

Upton Park's final victory over Chelsea was the special one.

We think it's fair to say that things haven't exactly gone to plan for Chelsea today.

The Blues arrived at Upton Park in desperate need of three points to revive their flagging season. Then they conceded. Then Nemanja Matic was sent off and they had a goal controversially disallowed. Then Jose Mourinho was sent to the stands. Their first half is best described with one word - "meltdown".

Shipping a huge goal to Andy Carroll hasn't exactly helped matters. Their title defence is seemingly in tatters in light of the loss to the Hammers. The huge pressure on the players and manager shows no signs of abating any time soon.

And the people of Twitter think it's ridiculously, absurdly hilarious.

The reaction to such a spectacular implosion was always going to be amazing. Without further ado, here's the very best (and funniest) of the Chelsea-related trolling. Sorry, Jose.
