To be honest Chelsea were scoring a lot of goals in the first half of the season, and the talk of them playing boring football has only come about this last month when they had Costa and Remy injured. At the end of the day like Carragher said, they got themselves in this position where they can afford to slow down and just grind out results. I believe only Man City have scored more goals than them this season, so for Arsenal fans to chant boring Chelsea is a bit silly when despite being built on free-flowing attacking football, still cannot score as many goals as Chelsea.
