What Mourinho did right
1) Picking pace over experience
Selecting Kurt Zouma over Gary Cahill ensured that Sergio Aguero could be caught around the penalty box (not a good sign for Cahill though).
2) Pulling back midfield
Mourinho spent most of the match screaming at Ramires and Nemanja Matic to hold their positions. They pulled back. It wasn't always pretty, but it worked.
3) Attacking the left
Manuel Pellegrini made a mistake in starting with Bacary Sagna instead of Pablo Zabaleta. Mourinho let him know by piling on the pace of Hazard and Loic Remy on Chelsea's left.
What Mourinho did wrong
1) Arguing all the time
Every decision was wrong. Every decision was contested. He had to be spoken to by the referee for constant abuse on the touchline.
2) Shouting in the tunnel
After the game, Sky Sports staff were abused in the tunnel for their so-called "campaign" against Chelsea. Pathetic.
3) Media blackout
Mourinho refused to talk to the media, denying not only the press, but the game's fans and Chelsea's own supporters.
4) Can't let it go
Even in the club programme, Mourinho referred to those who weere criticising the club, making him look childish.
5) Defending Costa
He defended Costa's awful stamp on Liverpool's Emre Can publicly. And then he defended it a second time by not talking to the press, in protest at the Spaniard's three-match ban; irritating behaviour beyond belief.
