Completely agree but it just so happens that the majority of this team is suited to that style of play.
I agree, the problem is that we don't have a system. If we lose one player say Ben Arfa for instance at times we've completely changed the shape and formation to accomodate his replacement. It will be a lot easier for us to supplement the type of players we have with like for like replacements. As it looks like Pardew will be here for the short term at least we need to decide on a system and build the team around that.
I'm not a massive fan of Martinez but he seems to have his formation and stick to it, look at the cup final for instance. His usual right wing back was injured so he moved arguably his best player to fit the system they are trained in.
