You have pretty much repeated my assertion about Reus. He starts from the left and he gets somewhat of a free role in his actual forward play, which fluent and fluid. SO tell me? Why actually play him from a different position to the one he plays so well from at Dortmund. I repeat, if this is his natural game and it works from where he has been so far (starting from the left), what is the actual need to start him at CF, where the emphasis and starting position changes as its proximity approaches the CB's?
Isn't that is how Suarez and Aguero play? Despite starting as CF,they drift all over the pitch (free role) and don't like to be squeezed between two CBs.
