Can you blame them? Most teams in the Champions League would settle for a draw in the away leg... especially against Barcelona who are so strong at home.
If they had gone to Barcelona trying to win they'd have got battered... as it stands now they will be favourites to progress to the final. Barcelona didn't adapt to Chelsea play quickly enough and were still trying to pass it through them.. which wasn't working due to sheer numbers back, and Barca didn't realise this. Only in the 85th minute did they start putting longer balls into the box and crossing, and they nearly scored 2 as a result, including a real sitter from Bojan.
It wasn't as if Barce were unlucky.. or missed shitloads of chances, or had refereeing decisions go against them.. they were just made to look extremely ordinary and Chelsea deserve full credit for that.
That's all well and good except that Chelsea team was put together for hundreds of millions and were still afraid to attack.
Barca are still favourites, Chelsea have to stop them scoring and try and score themselves.
