Benjamin Sesko is "impatient" to be back playing and could be fit again sooner than was expected, says his agent.
Sesko joined United in a £73.62million deal in August but he has been sidelined for a month since limping off against Spurs in their 2-2 draw with a knee injury.
United rose to sixth in the Premier League table with a
4-1 win at basement club Wolves on Monday night.
“Benjamin feels very good, his rehabilitation is going according to plan," said Sesko’s representative, Elvis Basanovic.
“He can’t wait to get back on the pitch. He’s missing matches, he’s a little impatient and we hope that he will return soon, to be where he feels best again.
“It’s hard to say exactly [when he will return], it will ultimately be decided by the medical service and the coach.
“I think we will see him on the pitch very soon. Maybe sooner than it seems at the moment.”
Sesko scored two goals in 12 appearances before his lay-off and he was dropped for the away games at Liverpool and Tottenham.
The Slovenia international was United’s fourth-choice target up front after Liam Delap opted to join Chelsea, Viktor Gyokeres favoured Arsenal and Aston Villa refused to budge over Ollie Watkins.
Sesko arrived in the same summer as Premier League-proven pair Matheus Cunha and Mbeumo, yet the trio have only started three games together.
Amorim has settled on a strikerless system since Sesko's injury, with Mason Mount becoming an increasingly influential figure after his third goal of the campaign at Wolves.
Basanovic believes Sesko just needs more playing time with Cunha and Mbeumo when he does recover from injury.
“I must say he (Amorim) received Benjamin excellently,” Basanovic added. “I think Ruben is first of all, an excellent person with fantastic charisma, extremely intelligent, emotionally intelligent and I think he knows what he’s doing.
“I believe he’s in a difficult situation. It’s not easy to build such a project that requires enormous knowledge and amount of time. United is one of the biggest clubs in the world, if not the biggest and people don’t understand you need time.
“But I think every team being built needs time. Just look at Cunha, Mbeumo and Sesko: they have played very few matches together. And I think that they especially need games and they need to develop certain automatisms because then it’s much easier.
“When you have these automatisms, you don’t need to think where a player is or runs but that you start automatically. Then the results come and everything looks much better.”
