Chelsea had more attempts at the goal than Barcelona.So their form is based on the exact point where they didn't capitulate against any half decent attack? Why not talk about the last 15 minutes of the Sevilla game where we were quite good for our form as well then?
Chelsea in the last 3 games have played two shambolic teams and one team that has Chelsea as their bogey team. Even then they were poor at the back throughout the whole game and had to rely on Willian to bail them out.
Both Chelsea and United are dysfunctional teams; both of their defences are error prone and their attack is very individualistic. Both are incidentally classical defensive managers and so will generally have the same outlook on this match.
I honestly don't remember Barca being extremely dangerous in Chelsea's half, except the incident with Suarez just before the goal and the goal itself. Had Willian had a bit of luck, Chelsea could have got a very positive result against one of the definite favourites in the CL, whilst we got totally outplayed by Sevilla, who have scored the least amount of goals in the top 10 of La Liga.
