In response to Rashford's exertion, Amorim says, "I'd rather put GK coach, 63, on bench."

Marcus Rashford has been publicly humiliated by Manchester United head coach Ruben Amorim, who has stated that he would rather to bench the team's 63-year-old custodian coach than the striker because of effort.

In the 1-0 victory at Fulham, where Lisandro Martinez's deflected goal was Amorim's team's lone attempt on goal, Rashford was once again left out of United's matchday squad.

Rashford has not been a member of United's Premier League matchday squad for almost two months, and according to Amorim, he does not have the mindset of someone who is "giving the maximum every day."

Amorim stated that "if things don't change, I will not change" in reference to Rashford's place in the United team, with just one week until the January transfer window closes.

"The same explanation is always given: the training, which is what I believe a football player ought to do in life. In his post-match press conference at Craven Cottage, Amorim explained why Rashford was unavailable by saying, "It's every day, every detail."

"I won't change if nothing changes. Every player is in the same predicament; if you take the most appropriate actions, we can utilise every individual.

"As you can see, we are a little slow on the bench. However, I would rank [Man Utd goalkeeper coach Jorge] Vital higher than a player who doesn't always give their best effort."

Later on Sunday, Rashford congratulated his teammates on their victory and shared a "well done" comment on his Instagram story.

Vital, a 63-year-old United custodian coach, joined Amorim at Old Trafford from Sporting CP in November.

Amorim: We struggle to score goals because Manchester United lacks speed and strength up front.

The United manager acknowledged that his team still struggles to score goals this season and that they lack "pace and power up front" before Amorim made his remarks on Rashford.

For the 12th consecutive Premier League game, United failed to score from open play in the first half at Craven Cottage on Sunday. They also had to wait 42 minutes for their first attempt at goal, a weak half chance from Matthijs de Ligt.

Amorim acknowledges that his forward line could use some work after Rasmus Hojlund was substituted around the hour mark after making minimal impact and Joshua Zirkzee only touched the ball eight times in the final 30 minutes.

Asked if scoring goals is a problem for his team, Amorim told TNT Sports: "I think so. Even in the second half we wanted to change something, we lack some pace and power up front.

However, that is the reality. We need more opportunities and ball creators. We have a lot of trouble with these details. However, winning greatly aids in improvement.

"We have to be cautious," Amorim said when asked if he anticipates any additional assistance during the final week of the transfer window. We are required to abide by all rules, including this one.

"We can't do it today because we made [transfer] blunders in the past. Let's see. Our goal is to make the team better. Let's concentrate on our current players and the upcoming match.

Amorim is uncertain about Garnacho's future.

Alejandro Garnacho began in the victory over Fulham but was substituted following United's victory, but Amorim was evasive about his future.

Chelsea and Napoli have expressed interest in Garnacho, and United may be persuaded to sell the academy graduate in order to generate "pure profit" money to support their compliance with the Profit and Sustainability Rules (PSR).

"No one is aware. Regarding Garnacho's ability to go before the February 3 deadline, Amorim stated, "Anything can happen."

"He's getting better at every aspect of the game, even how they recover and comprehend the rules when they defend.

He played a little more openly today, not so much within, and I'm trying to figure out what position might work best for him. We need the guys to fight each other, but I'm not sure what will happen."
