Manchester United manager Ruben Amorim has been blamed for causing one of his players to "lose confidence" after replacing Erik ten Hag.

The United boss needs a couple of transfer windows to build his ideal squad and his current squad doesn't suit his preferred formation and style of play.

Amorim's appointment had a negative impact on Alejandro Garnacho, with the Manchester United Academy graduate finding it difficult to settle into the role of a number 10.

Amorim will be keen for Garnacho to make a difference in Manchester United's Europa League quarter-final first leg against Lyon on Friday night.

Ahead of this game, Lyon star Nicolas Tagliafico blamed Amorim for causing Garnacho's decline.

"When he first came into the team, I saw the good in him, but with the new coach and a different style coming in, he probably lost some confidence," Tagliafico said.

'It's not easy when you miss a chance as a winger at a club like Manchester United.

He added: "I know he's had some difficult moments under the coach, but he may need more support on the pitch.

"Sometimes it's more about communication. When a winger plays in front of me, I like to talk to him. Encourage him to try more one-on-one or tell him when it's time to adduct. He was still young.

'Maybe that's what he needs more at Manchester United. But he's fast and talented. He can be a star. ”

This summer will be crucial for Manchester United, with Amorim explaining why the next transfer window is 'crucial' for the Premier League giants.

"It's crucial. We are doing everything as soon as possible. You look at the team's schedule, we won't be in the Club World Cup, we're going to have a pre-season," said Amorim.

"You look at the next few years, we're going to have the World Cup, it's the European Championship. This window is very important in consolidating our foundations.

'It's clear to everybody here that it's very important and we have to take advantage of that. We won't have another pre-season. It won't be like that.

"We need to do everything as soon as possible to get everyone ready for pre-season after a season like this.

"We need to show something. This is not an argument. I don't want to hear that we need a lot of time. It may take us time to win the league but after this season we need to improve a lot. ”
