mango chow i don't know why you were surprised, in this game it was the same script that plays out season after season..
Arsenal does look better with the possession and pretty touches for about the first 15-20 mins of each half and chelsea just soak up the pressure and aim to hit them on the counter, with a long ball or from a set piece.. Then chelsea use their physical presence to overpower all their smaller players and by the time you score one on them their brand buss..
Of the top 4 EPL teams, Arsenal is always the easiest to deal with for Chelsea because its men against boys.. No steel in that Arsenal side and the setta small touch just plays into the hands of the strong chelsea back 4. I laugh when i see Arsenal getting outmuscled by Essien, Mikel and Lampard in the middle, then Wenger replaced Song with an even weaker player in Walcott. The game was over as far as i was concerned right there and then.
the only thing standing in the way of chelsea and the title this year is the African nations cup, and even that i dont envision to be a big problem.
