Not a Fellaini hater but here's the thing though :
1 He might've had decent games against West Brom, Crystal Palace and teams of similar calibre. But then any top half central midfielder will have decent games against them. Does that justify them having a starting/ squad role for United, a team that has been contending for league trophies and European Cups for the past 20 odd years. For a player worth 28 million you'd expect him to perform against the big boys. And he hasn't done that in all honestly, especially against Bayern where his acute lack of technique was on full display. We as a club should aspire to having the best technical players around. We've had it in the past with Robson, Ince, Keane, Scholes, Carrick. Some really great names have graced our midfield. That's the level we should be aiming to get back to. Unfortunately Fellaini just doesn't cut it, even at his best Everton form where he was a brute #10 and a focal point in their side. He's just not a defensive midfielder, he doesn't have enough awareness, has little discipline, fouls constantly and most importantly doesn't have the engine. Those are things that can't be taught to a player of 26, he's set in his ways. To make him succeed we'd have to sacrifice Rooney/ Mata/ Kagawa and play Fellaini as a #10, his favoured position at Everton. There's nothing wrong with saying he's not United quality tbf. It's not hate. Sometimes you make a mistake, but you have to move on and rectify it. Plugging you finger in the dyke will only work out for so long.
2 It could be argued that letting him go now would be the humane thing to do. He's been made a scapegoat, a floppy symbol of the previous manager's tenure and the psychological impact on the poor guy can be devastating. If he has a season similar to what he had last year I can honestly see the crowd turn on him on top of his value deprecating further. Right now he has some remnant goodwill from the Everton days, that's still in public memory. If he has another poor outing most teams wouldn't be interested in him. I think the best thing to do now is offload him while he still has some value in the market. We'll recoup maybe 10-15 million to add to our transfer budget + we'll free up wages for an incoming player. It's a win-win honestly for both parties.
