What problems did the Manchester United coach expose when Manchester United lost to Atletico Madrid?

Atletico Madrid beat Manchester United away 1-0 and reached the quarter-finals of the Champions League at Old Trafford. This game is the standard version of Atletico Madrid's victory. The defensive system of five defenders and the arrow players of three defenders focus on surrounding each other. Simone's team, as always, has high execution and highly unified tactical thinking. Give up possession and possession, and hit your defensive counter-attack quickly through midfield. We predicted it before the game, but I don't think the problem of players is very big on Manchester United's side. The most responsible is the head coach Lannick.

The first question is, when we know that the opponent has a high probability of playing the fifth middle position, why not go to cavani to help Cristiano Ronaldo share the firepower of the three central defenders, so that Cristiano Ronaldo is surrounded by the three central defenders and basically loses the chance to shoot.

The second question, why did you replace Elanga, one of the few wingers in the first half, with La Herford? I also mentioned that the hero La Herford can't play on the right wing because he can't cross. He plays on the left wing, looking for inner space, which is a threat. Playing right avant-garde is casting pearls before swine. Fernandez played well in the first half and played a little early. If cavani replaced Sancho and Bogba replaced Fred or McTominay, would the result of this game be different? Fernandez's attitude towards Cristiano Ronaldo has obviously changed, which may be bad news for Portugal. Lannick obviously doesn't want Cristiano Ronaldo to be the core of this game. Even though he knew it was possible to win by playing beside Cristiano Ronaldo, he didn't want to play like this. We don't know the exact reason.

But as far as this game is concerned, or as I said and emphasized, I think Ronnie is the worst head coach in Manchester United's history. No matter from the tactics, technology and control of the locker room, or the control of outside public opinion, he is very poor, and the difference can not be worse. Congratulations to Atletico Madrid, you deserve this victory. Messi and Cristiano Ronaldo didn't reach the quarter-finals of the Champions League, which is actually a bit embarrassing and regrettable for fans.
