He's done brilliantly in his advanced role for us (especially this season) but I'd like to see us move away from the combative #10 type and play a real playmaker there, the huge presence of Fellaini and Cahill before him has/had far too often negated the fact that we had geniunely able strikers ahead of them.
Jelavic obviously plays second fiddle to Fellaini in our final third and his distinct lack of service has more often than not seen him drift out wide to pick up the ball, which has had us all fuming for a good 80% of the season.
Other teams have the likes of Bale, Mata, Silva, Coutinho, Sessegnon, Gaston Ramirez, Cazorla/Wilshere, Ruiz, Kagawa/Rooney playing these #10 roles and in essence we still have a mid-90's style centre forward taking down most of our attacks, with the money made from Fellaini i'd like to see a large chunk of it spent on a playmaker type, if Moyes is still here next season I doubt this will happen but hey, a guy can dream.
