The guy has previous. i read somewhere everything was agreed with Juve last season (i think) and it all went south. nothing is simple with Witsel
Was Zenit who pulled the plug mate on that, but shows that Witsels people are not adverse to making deals and trying to force peoples hands.
Suspect without any knowledge that are trying to play everyone off against each other to get the best possible deal.
Let us agree a fee with Zenit, Zenit announce he will effectively be leaving this summer (which they have done), then fanny us around and play us off against Italian teams who are unwilling to offer the same fee to Zenit, end outcome is either Zenit allow him to move for a lesser fee to Italy for example (and lesser fee = more in his contract i imagine), we decide to force the issue through by increasing our offer to him, or he sits out his contract at Zenit as his bluff is called by both Zenit and us, and he moves on a free next summer for even more money as no fees being paid
The player in this matter is really in a win-win situation as he knows he holds all the cards
