I know Herrera isn't a playmaker but think that's what we need most in our midfield if he or anyone else leaves, a deep lying playmaker. We need more passers in midfield, I don't feel we have that player that keeps us ticking, I think Pogba could do it if someone got hold of him and gave him a shake, he showed against Newcastle in the 2nd half he can do it but needs to mature as a player and stop dawdling with the ball and get drawn into physical battles, just keep the ball moving. If he can prove he can play that role then we need a more mobile defensive midfielder next to him that can replace Matic and Fellaini in the starting lineup. Think Pogba's best performances for us came when Herrera was his partner in midfield as he was more mobile and think that's probably why he performs much better in a 2 for France, though I heard he dawdled again tonight and lost possession for Germany's goal.
