On his day he is my favorite player in the squad. Since he's been here, taking away his price tag, he has been one of our best players (not saying much). Growing up being a fan of Ronaldinho, watching him play was fun and pogba is the only player in the united team since Ronaldo and Nani (yup, I loved Nani) who gives me that feeling, so on that level I'll miss him.
Regards to him and Raiola, we've seen people around players mouthing off before from Ronaldo (slavery comments), rooney (city debacle, which when you think about it is a bigger disrespect in my eyes), but in general I don't think Pogba has ever downed tools or can be accused of not giving 100%. He's had bad games, generally when the whole team has had bad games so it is what it is.
In the end, he came, won some minor trophies and will be gone. In context, when compared to our star signings since fergie left (Bruno, Sancho, Martial, Mhki, Lukaku, Zlatan, Mata, Depay) Only Bruno has had a better time here. Whilst I don't think it says a lot about pogba, I think it says a lot about all the other players that have been and currently are at United.
