I would be happy with Doucoure, Richarlson, Tierney. I think Sigurdsson could do a job as the ball playing central midfielder and Walcott could do a job alternating with Tosun up front. Also Lookman back as a first team regular and we all of sudden have pace and guile again. Too many signings again would making gelling difficult.
Hopefully Schnerderlin leaves to make room for Beni and Williams leaves to make room for Holgate.
