Alot of teams are doing the corner routine that swings the ball really close to the goalmouth, no thanks to Arsenal, and United seems to be suffering from it.What is it with them and corners? They're either constantly turning them or conceding from them.
Notice how Son scores a miraculous corner goal just a few days back before Cunha scores an exact replica.
United's way of defending corners seem to be putting one man to protect Onana, putting himself at armslength from other defenders, but Onana seems to be doing nothing with that protection.
