In the last few weeks, whenever he comes on, we don't seem to go direct and put him in the box; nor do we play him like we did last season as an attack-minded #8. When he comes on now, he sort of continues with Schweinsteigers role in that sitting midfield two, but with a little bit more hold up play. He's a sub, but he's not really an impact sub, though he does play well when he comes on IMO.
Earlier in the season and last season, he often came off the bench to a barrage of speculative long balls which was pretty ugly to watch, and didn't always have a great effect. When he started games last season, he played an almost Yaya Toure-like role complimenting the attack. It's like LvG sees him as 3 different players, depending on the game, and whether or not he's coming off the bench, but we've not really seen a glimpse of Fellaini's best form from last season. Most probably because we play a different variant of 4-3-3 which doesn't really suit him. It doesn't really suit anyone. The squad looks tailor-made for last season's backwards-pointing 4-3-3, but I don't think a single player is benefiting from the forwards pointing 4-3-3/4-2-3-1
