During the Premier League match against Arsenal, Ruben Amorim experienced firsthand how difficult it can be to be the head coach of Manchester United.

The coach’s team’s defensive stability was undermined in the second half by two goals from corners.

When the Gunners win a corner, they run in from behind the back post, pack the opponent’s six-yard box, and score goals frequently.

The cameras captured Amorim in the dugout, looking utterly despondent following William Saliba’s goal.

His arms were on his hands, and he appeared upset and anxious after realizing that the game was essentially out of his grasp.

It was Ruben Amorim’s first loss as manager of Manchester United.

Before Matthijs De Ligt was denied a goal halfway through the second half by a spectacular stop by David Raya, Amorim’s team hardly had a chance on goal.

However, the 13-0 corner count spoke for itself. Given that Arsenal is unquestionably the experts of the set-piece, you really cannot afford to give them so many opportunities.
