Where's he going to play?
Koeman's central MF looks pretty settled - Schneiderlin, Gueye, Davies, Barkley.
Everton need wingers (Rooney hasn't the pace anymore) and good striker or two (Rooney isn't that anymore). He'd have to take a massive wage cut and maybe he will.
Would prefer Ebepton spend that money on players who will actually play. If signing him is for leadership and training room glue, he'd be better off going to China for a couple of years, sacking away silly, silly money then come back to Ebepton and start working on his coaching badges and following the Big Dunc model.
