Aguero, Van Persie, Toure, Silva, Sturridge, Hazard and maybe Di Maria, Mata, Fabregas and Sanchez if they recover the form they showed for other clubs, could all arguably lay a claim to be the best player in the league. It's always hard to say though. Different positions and all. For example, if you take midfielders, Ramsey and Fernandinho enter the equation and so on.
