I agree with you especially about the mobility. Caz,Wilshere and Ramsey all have fitness issues. There's also the the fact that Ramsey and Wilshere lack some tactical awareness and don't track back quickly. I won't write off Coq as he can go up a level if he improves his forward play. There's a strong minus with all Xhaka's partners. We need to get as close to the Kroos/Modric, Veratti/Krychowiak and Busquets/Iniesta model as we can. That will give us a great platform going forward at pace (and when being countered) especially if we get a goal scoring forward who is consistent.I think we need someone with mobility. Wilshere can be that player if he stays fit. Elneny, Coquelin and Cazorla will share game time I reckon depending on the opposition until Wilsh is ready.
