Look, I'm as large a proponent as anyone for having a decent section of the squad be young players, but if anyone thinks that Vidal is old, then they are either A) 13 years old B) Demented.
or C) @Hustini
In all seriousness though, I don't think it is an issue of his age being a factor in his playing ability, but moreso the window of opportunity to sell him before the returns diminish even further.
As far as this dude, I have no clue who he is
