I thought Chelsea did what they could.
No Hazard and Etoo, who are key to the counter attack. Oscar wouldn't have been suited to this game without them. Missing Ivanovic, Ramires, and Matic who is cup tied. Im pretty sure Jose would have taken 0-0, got them 4 key players back and gone again at home.
If he didn't have injuries then he would have lined up how they did when they beat Man City away 1-0. You cant win the game in this leg but you can lose it.
