Knowing Rabiot the problem is probably on his side, I wouldn't be surprised if he declined offers from clubs that didn't guarantee a starting spot, if the rumours are true Bayern, Madrid, Barcelona, Tottenham and Juventus have contacted him. While he is a good player, he isn't guaranteed to start for at least 4 of these teams while Tottenham probably don't offer enough money.That's positive then, honestly I don't know much about the guy.
It could just be that we will get lucky for once been able to offer the wages, and a place straight in the team, which must be appealing no matter how bad we are just now, maybe this will do the trick with De Ligt too.
