Valverde is making a horrible mess of the squad rotations.
Overplays certain players to the point of running them into the ground (Messi, Suarez, Busquets, Iniesta)
But at the same time, keeps chopping and changing the newbies, notably Semedo, Coutinho and Dembele. Starts them one game, where they play quite well, then gives them 10 minutes off the bench the next game. Looks like he successfully ruined Semedo’s confidence that way, is he trying to do the same with the other two? How can they have any sort of form when they have no continuity?
Also, he needs to stop playing Coutinho on the right. He’s found all his success as a LM/AM/LWF, so Valverde plays him on the right?
