I don’t agree. In Arteta’s system he wants his two wide men to isolate the full back and beat them. Zurich were so bad that he didn’t need to do that but against better opposition, Marquinhos needs to be braver imo.
I mean, sure. But this seems like pretty high standards for a teenager who just created two goals in his first ever professional game in Europe. The kid probably just wanted to keep it safe and not screw up in his first game by losing the ball in 1-on-1s.
