If Xavi isn't happy with Frankie it's because Frankie hasn't set the world a light since being here, If he was constantly playing at a WC level the decision would be more difficult, but probably still the same, I think he is currently our highest wage earner & the club is trying to cut over 100m off its wage bill.
So when you have a young players, on high wages, who no doubt as potential to be WC in the right system, but has never showed it for us consistently, he's only gonna be the first to go under our current economic situation.
But for people to constantly make this a busquets vs Frankie debate doesn't take into consideration everything, they don't even play the same position.
We have to sell & cut our wage bill to buy, Frankie is the most saleable assist that hasn't really delivered he hasn't showed himself to be a 80m player.
