I think that if Pogba signs he should partner Fletcher in some games and Scholes and Carrick should start the others.

I say that Pogba should play alongside Fletcher because Scholes and Carrick, brilliant as they are, aren't great communicators and Pogba needs to learn; needs to be taught, his role. Fletcher is a talker and an organiser and was Pogba's coach for half a season. Pogba will come on immensely if played alongside Fletcher. Twenty starts alongside Fletcher will turn Pogba from a kid with attributes but poor application into a potential first team player.
