Liverpool aren't that great defensively, just recently the teams haven't offered any attacking threat.

Liverpool are probably the best team in Europe in regards to defensive ability. They seem impossible to penetrate at times.

My comment was in reference to the last few weeks where Lucas hasn't really featured and Alonso/Masch have been organised sublimely in front of a reliable defence. They made Man Utd's attackers look uncreative and average imo, and I don't think I've seen that this year besides that game (for 90 minutes)
Manchester United / Aston Villa / Real Madrid were awful, Liverpool were good, very good, but they only looked so good because of the appalling form of the clubs they have played.
