Manchester United head coach Erik ten Hag has "a strong belief" that Marcus Rashford will soon overcome his early-season problems to become a regular goalscorer once again.

The 25-year-old proved to be the team's standout player last season, scoring 30 goals and registering 11 assists in 56 appearances in all competitions.

However, Rashford has struggled this term, only managing one goal and three assists in 12 appearances, and he again found it difficult against Copenhagen in the Champions League on Tuesday.

There have recently been suggestions that the England international could be dropped from Ten Hag's starting side if he is unable to navigate his way through a difficult period.

However, the Man United head coach has insisted that he still has "trust" in the club's academy product, who is set to keep his spot on the left of the attack against Manchester City on Sunday afternoon.

"Give him the trust and play him every game, most of the games he finishes every game, so I have a strong belief he will return to scoring a lot of goals," Ten Hag told reporters during his press conference on Friday.

The Dutchman also addressed the team's lack of goals as a whole this season, with the Red Devils scoring just 11 times in their opening nine league matches.

"The cooperation has to click, but we showed this week some examples where there are so many we have overload positions, going in overload position to the opponent's goal and we don't net or don't even hit the target," he said.

"We don't have time to train this, we give some coaching and I'm convinced with the quality from our players that they will go and score more goals."

Ten Hag also said that Andre Onana has made "good progress", with the club's goalkeeper producing a match-winning moment against Copenhagen on Tuesday when he saved a stoppage-time penalty.

"You give him the standards and also the expectations, but also it's about getting to the same level. He has high expectations from himself," he added.

"We give him the confidence, look what you did in the past for great clubs in great leagues, you have the ability and the skills. The last two games were good progress, now we have to keep this going. It's very good but at Manchester United good is not good enough."

Casemiro remains a doubt for the Manchester derby due to the problem that he picked up on international duty with Brazil, but Aaron Wan-Bissaka is now back in training following a hamstring issue.

Man United have five more games before the next international break, including a EFL Cup contest with Newcastle United, and the return Champions League fixture with Copenhagen in Denmark.
