I'd be all over this signing and if Rabiot is smart, he should be considering leaving PSG. He's played well this season and missed out on going to Russia. He's spat the dummy out a little bit because of it and refused to join Frances reserve list, but personally I don't see that being a problem.
He won't give up making plans for his time off in the summer to be a reserve to the bench for his country in the World Cup. He's smart enough to realise how badly things would have to go for him to actually even play so why bother.
He was shown around the training ground etc a few years back when we were linked.
Then I think his Mum piped up about something and he decided to stay at PSG
