See, you would have a point if it was just Berbatov...Rooney and Giggs both were the same with Nani! Maybe not as much, but the actions were very much the same. It wasn't because Berbatov had some personal dislike with Nani and couldn't get over it, but that players were frustrated with his inability to act in the final third.
Also, when is Berbatov allowed to do this then? You are saying it's okay for Giggs, Scholes, even Rooney because they are senior figures who have been here for a long time. So if everyone played Berbatov shite balls through for the first year, he could never complain as he's not been here long enough? That doesn't make much sense, a player will complain regardless of how long they've served the club because the one thing they are being paid to do is perform, and when that doesn't happen, whether it's down to you or someone else, frustration will be expressed. Some deal with that like Scholes are prefer to molest opposition players legs, others react within the team.
This is the point. Berbatov was doing no better than Nani a couple of seasons ago. Half of the time, Nani's "mistake" seemed to be an inability to read Berba's mind.
To my mind, Berba had absolutely no right to be having a go at anyone. He had to get his own shit in order first.
Now he's doing well, I wouldn't mind if he had the odd pop at others. He's been the main man this season. Strangely though, he doesn't seem to be doing it half as much now.
