He won't be like that all the time, and Jelavic didn't get involved all night or have anything to feed off.
Fellaini was great for most of the game in the oppositions half. When we needed someone to put of footy on the game, break things up by the 70th minute we didn't have anyone there with Fellaini up top.
When he dropped deeper, we had no outlet because we lost him from that final 3rd to hold the ball.
He can easily get box to box. But adding his ability to disrupt all over the pitch and talent to control the game, sticking him in the middle to get up and down means he can dominate all over rather than the opposing half.
Playing 2 creative attacking players on either side, and in front of him would benefit the attack creatively for Jelavic for eg.
It'll just improve us in keeping the ball which is always something we lack when it really matters
