Manchester United lost to Manchester City 0-3 in the Premier League, and Robbie Savage commented on the game after the game.

Savage said: "If I were Manchester United's head coach, I would change the formation immediately, and this formation would not work."

"As the head coach, you must make a major decision, and everyone can see that Amorin's formation is not working."

"I understand the principles and the philosophy of football. I understand all these, but 3-4-3 is not working, and it has been a long time since it has not worked."

"As long as you continue to use this formation, you will not be able to score the goal at the ninth position."
