Sczc, Ox and Wilshere are the type of "potential" we need. Along with experience of players like RVP , Vermaelen , Arteta , Kos , Song and Sagna.
Walcott needs to work harder , just make a general nuisance of himself on the pitch. He has that stamina - one would think.
About Coquelin , we need to see him in his preffered position for a longer spell.
