Would be perfect, was easily one of if not the best midfielder in the league in his last year with Southampton
Out of the load of centre mids we got linked with (Witsel, Carvalho, Strootman, Schneiderlin) he was always going to be 1. the most available as far as the level of competition for him - as most CL English teams had passed on him in the past for whatever reason. 2. the most likely as far as the owning club being willing to let him leave - not a 'star' name, not really a fan favourite, and at an age where he has already had that 'big move and it hasn't worked out for him. 3. Lives local, had his best season under Koeman etc
Hopefully i'm right and we do try get him, a midfield of him and Gueye would be a dominant one, throw in a fresh and rested Barry for a full season and yeah think we could allow the creativity to come from other (wider) areas as lets face it we'd not concede many at all
