Manchester United boss Erik ten Hag admits he is "not happy" with Marcus Rashford's current form but is still backing his No10 to come good.

The England international has scored just one goal from 15 appearances in all competitions this season and was shown a straight red card in Wednesday's 4-3 defeat at FC Copenhagen in the Champions League.

Gareth Southgate has kept faith with Rashford by naming him in the latest Three Lions squad — and Ten Hag expects to see improved performances from the 26-year-old moving forward.

The Dutch manager said: "I think he's [Rashford] not happy, we are not happy. We have an expectation. He has high expectations from himself. In this moment he is not in the best form but I know he will be back.

"I know when the team is playing better he will play better. He will go and score goals. I am confident of that. This season he will improve and score goals. 

"He is totally in the team, he is aware of everything so I think he will be back on track.

"It can happen very quickly and sometimes you only need one game. I'm sure he will get there."

United's defeat in Copenhagen was their ninth in 17 matches this season, making tomorrow's Premier League meeting with Luton a must-win for Ten Hag.

When asked whether recent results have been acceptable, the Red Devils boss replied: "It is about the end result and we have to win every game, so we are very disappointed to lose any game but finally it is about the end result.

"It is always about being in a process, thinking about a process and then it's about managing the process. That's the only thing I focus on.

"I think we have often proved we can, like at Fulham, like Brentford, that we can overcome big setbacks."

Rashford should return to United's starting XI against Luton after missing the 1-0 win at Fulham last weekend, although Ten Hag confirmed centre-back Jonny Evans will not be present at Old Trafford after picking up an injury on Wednesday night.
