OK, what I see different to the Kenwyne Jones/Scott Parker/Puncheon situation is this :-
Bologna have accepted our bid for Gaston, I think that is 90% certain.
We have agreed terms with Gaston, I am 100% certain that that is 100% certain.
In the other 3 cases above no-one had accepted any offers from any clubs for the players in question (they were in effect tapped up via the media)
Therefore Gaston, in my tiny world anyway, is perfectly in his rights to try and get Bologna to get their asses in gear!!
