Obviously Belgium have not played him because he has retired from International football. Anyone with any sense would have kept him at least for the time being while getting rid of much more useless players. He played for Belgium in the WC and was very instrumental in getting them to the semi finals. If Belgium had used him in the WC why not Manchester United who has a much worse midfield than Belgium? Are you telling me that Lingard and Mata and Periera are better or more effective than Fellaini?
Kept him for what? You want to try to cross without aim?!? What am I reading here? Fellaini is everything wrong with that kind of football, and we are not going for that kind of football, full stop. At least have the decency to admit that we aim for better football than that.
Lingard regressed, but that was not expected. Mata is a technical player, yes, he is not the kind of player like Fellaini and can be more effective in a game, it all depends of the game. Pereira, despite his shortfalls, is still better than Fellaini technically speaking so yes. With Fellaini, our football would not have sustained. We aim to have players like Pogba or Bruno, not Fellaini. Thank you very much.
Or maybe a simpler question: who is the Fellaini equivalent at Liverpool, City, Chelsea, Arsenal, Spurs, Leicester, Barcelona, Real, Inter, Juventus, Bayern, even PSG?!? Please tell me who is that guy. And then wonder, if we don't have any equivalence, why would we need him?
