We don't necessarily need a 6ft 4 presence in midfield, I believe that's the whole point of having three men in midfield but we definitely need some athleticism in the team as a whole. Without Walcott, we've looked slow and ponderous in attack and, similarly, without Diaby or Song in there we've lacked someone who can just stand his ground and roll a few players off his shoulder.
Jack-Santi-Mikel can and will work most of the season but there will definitely be days when the passing and movement just won't work and we'll need players who can drive at the opposition. Whether they play out wide or in midfield doesn't matter.
