IF Vidal is needed to ask to leave it leaves him in an awkward position, this would be the biggest contract he has been offered in his life and most likely the biggest he will ever receive.
We are in a situation where we need to rebuild with big players, if we miss out on him and go for Strootman he wont be the top priority anymore, well esentially have his replacement leaving either staying at Juve for ultimately less money or going somewhere like Bayern who wont pay him anywhere near what we would offer or Madrid where he would be competing with Kroos, Modric, Illarmendi, Alonso and currently Khedira where he would get no where near the wage we are offering simply because they arent that desperate.
He needs to play this cool, if hes happy where he is in world football than fair play, he has the chance to achieve what so many rarely do. Its a hige oppertunity and I firmly believe it would be silly of him to pass it up. He will always return to Chile or Italy at the end of his career but even if its for a pay day he should be seriously considering leaving.
All signs point to the only thing holding this back is the official bid, I dont think we need to worry about the politics of him requesting to leave. All he would simply have to do is say "I love Juve, its part of my life, the club the fans. However I have been offered to play for one of the biggest projects in world football and the offer was a once in a lifetime opportunity, One day I will return, thank you to all the fans" It wouldnt be so hard for the board or the fans to swallow.
