The more I watch this guys video's, the more I'm convinced that even if we signed just him and Morata, Fabinho is that vital a signing we would be top 2-3 minimum in the league and we would be likely to reach knock out stages of CL.
He is an upgrade on Carrick, in the sense he is very 'press-resistant' and is so nimble on the ball, very Busquet-esque as you can't nick the ball off him, dude is ice cold in possession and very good at passing through midfield lines, so rarely passes it sideways or back.
Type of guy who could play CDM for any team in the game and excel. He'd take our possession game up a notch and 100% will get the ball off the defenders and ensure the passing back to De Gea to hoof days are gone. Very classy operator, who technically looked more than a match for likes of City/Spurs so instantly by having him, Herrera and Pogba in the same midfield, I think we'd probably end up having the best midfield in the league and more likely to hold our own in the big games.
