Mcry, Ney, and Messi combined well when they were all motivated before the World Cup. I don't see why Mcry, Vini, and Ham can't as well especially in Ancelotti's do-what-you-want style.
Maybe he could've developed at Girona or LA Galaxy. Maybe a proper coach here could reverse his regression although his magic the gathering IT nerd personality will probably always limit him.
M3ls would also know if he watched Arsenal at all during Arteta's stay that he was showing a plan on the pitch and was only hampered by quality of players which he now has. Whereas Xavi started his coaching with a better team than Arsenal when Arteta started and only gave us gimpball.
We all knew his fuck-you-terms contract would fuck us when he came to Barca. Fatporta was stupid enough to think Xavi could succeed to mitigate mortgaging some of our future on it.
