Did they try the Coritiba goal kick maneuvre?
Romeu slows things down, his awareness of the pitch is relatively small and takes a bit of time to expand when he’s facing away from the opponent’s goal. When he doesn’t get the chance to see and settle because he got pressured immediately, you see him apparently needlessly holding the ball up protecting it and risk losing the ball on Barca’s side of the pitch. (If you keep an eye out on it, you will notice moments like these happening too often, it will appear like he’s inviting pressure for no reason and not playing the ball away, it’s because he’s unsure of doing anything)
Now I also notice his defenders and keeper being a extra wary of passing to him if he doesn’t have way more space, because he turns slow and makes decisions slow.
He works best letting Frenkie do the attacking part of the job.
This is not the first time Yamal created that space with two players on him, they fear him and always double up on him, it’s the first time players were moving inside the box and the player with the ball having the balls to make that cross.
