I'm not trying to compare Fellaini as a player, to the talent of Fabregas, I'm saying we purchased someone who wasn't playing the role we intended for him here at his original club and assumed he'd adapt back, similar to Fabreagas.
The same logic for Mata, saying he'd play well anywhere due to being such a good talent, yet we've seen him not being able to perform on the our right (despite the fact he used to play there at times for Valencia) compared to the no.10 role, just because a player has bundles of talent doesnt' autoamtically conclude they'll adapt to a differing role in a different side, is my point.
The player we actually needed, the one who would have fit like a glove, and played the same role was actually Modric.
