I actually tend to believe TS the most right now,since being first on Vidal leaving report,they were good without many BS contradicting headlines.
According to them,deal with the player is not a problem and he gave his ok for the move.
And our first offer(after understanding that loan is not an option) is 20M(15+5M bonuses).Schalke wants 30M.
It MAY be closed on 25M.but that's just an opinion.
