Need two at least mate, Tims not good enough, Armstrong is too young, Doucoure left, Mangala left, basically leaves us with a 36yo Gueye and Jimmy G, with Alcaraz at a push a third option - but one Moyes I don't think likes there.
I'd say we need 2 plus another who may be able to cover there also.
Given the comments on extending Gueye I honestly think Moyes would love to upgrade both him and Garner this summer.
Trying to think back but don't think Moyes midfield when first here ever had an outright defensive midfielder really unless my memory is playing tricks. Maybe Fellaini was the closest....
