No other Catalan source has reported that Umtiti is likely leaving or negotiations have stalled due to the wages Sport Claim he wants.
Before anyone says "Well Sport has got some things right" doesn't mean it clears their reputation of posting rumors that are either bogus to get clicks or really exaggerate things that are going behind the scenes.
Sport in general was never high on Umtiti, even before we signed him they published rumors on how Lucho didn't want him as they feel he wasn't good enough and we are going for the likes of Marquinhos instead, or the gem during the summer how Valverde wasn't impressed with Umtiti at all and wanted Inigo Martinez to play alongside Pique.
Their last couple of articles come off as a Hit piece on Umtiti, trying to paint him as the bad guy that arrogantly wants to be on the same pay grade as some of the most prestigious members of the squad such as Iniesta,Pique,Suarez etc. and because of this he is willing to move to Manchester United.
Does Umtiti want to make more money? no doubt but I highly doubt the situation is anywhere near Dire as Sport is claiming and Umtiti would seriously leave Barcelona that easily because of these crazy Bullshit wage demands Sport claims.
