New Manchester United boss Ruben Amorim celebrated victory on his Old Trafford debut thanks to a thrilling 3-2 Europa League triumph against Bodo/Glimt – but admitted to a sense of anxiety as his players try to understand his demands.

The scream of relief the 39-year-old let out as Rasmus Hojlund scored the first of his two goals to level the contest at half-time underlined the strain Amorim is under.

The Portuguese has moved clubs – a third of the way through the season – with a determination to implement a wing-back formation United have no recent history of using. And this at a point in the campaign when fixture congestion is at its greatest.

Amorim had two full training sessions with his entire squad before his first game at Ipswich on Sunday, and two more in the build-up to this European success.

He has already revealed his only was round the situation is to push those who don’t start matches through full training sessions the day after. And Amorim is not sure how it will work.

“I get anxious because I don’t know what will happen,” he told TNT Sports. “We don’t control anything at the moment.

“I don’t know the players and we have not worked a lot together.

“We go to the game excited, but at the same time you are nervous because you don’t know how the game will go.”
