Marcus Rashford remains ready and willing to answer Ruben Amorim’s call should the Manchester United manager end his exile and has been undertaking extra training in a bid to maintain his fitness, Telegraph Sport understands.

The England striker has not played for United in nine games after being frozen out by Amorim since the head coach dropped him from last month’s Manchester derby over the player’s performances in training and general attitude.

Rashford, 27, is facing an uncertain future at his boyhood club with several European sides having explored the feasibility of a loan move this month. Borussia Dortmund are continuing to look at a loan and a host of other clubs, including Barcelona and Monaco, have been linked with the player.

AC Milan had discussed a deal for Rashford but were unable to sign him and England team-mate Kyle Walker, who seems likely to move to the Italian club from Manchester City.

But there are no guarantees Rashford will leave this month and it is understood the player has been doing extra training privately away from United in addition to training with the club to ensure he is as ready as possible should Amorim opt to bring him back in from the cold. Rashford is understood to have trained at Carrington on Sunday while his senior team-mates were preparing to face Brighton.

Sources close to Rashford insist he has no issues with Amorim and is ready to give 100 per cent to the team if he is picked again.

United face Rangers at Old Trafford in the Europa League on Thursday and Rashford is waiting to discover if he will be recalled. He has not been involved in eight of the last nine match-day squads and was an unused substitute in the 2-0 defeat at home to Newcastle.

Amorim defended his continued exclusion of Rashford after Sunday’s 3-1 defeat against Brighton at Old Trafford – the 10th league loss of the campaign – despite worsening results and United’s struggle for goals.

“Guys, like you said it’s his choice,” Amorim said of Rashford. “In the last games that we lost, Rashford was not here. So I don’t want to put this moment on Rashford.

“Rashford is out at this moment because he’s not playing. No matter what, I’m not going to put [in] a player that I don’t believe is the best for the team.”

Although Rashford said last month in an interview in the days after his derby omission that he was “ready for a new challenge and the next steps” in his career, he has never formally asked to leave the club.

However, United are ready to offload the player this month in a bid to free up money on the wage bill. Rashford’s £325,000-a-week salary is a complicating factor for potential suitors interested in a loan and the reality is United would have to subsidise a hefty portion of his wages for a deal to happen.

A move to Saudi Arabia would have been presented a potential financial windfall for United but Rashford rejected offers worth up to £35 million a year because he wants to play in a competitive league that will give him an opportunity to regain his place in the England squad.

Meanwhile, United’s shirt sponsor, Snapdragon, will replace their company logo with the (RED) branding on the front of the jersey for the team’s Premier League match against West Ham on May 10 in support of the global fight against health injustice. The women’s team will wear the same logo for their game against Arsenal on May 11.

Under the terms of their sponsorship agreement, Snapdragon can nominate a charitable organisation to replace their usual logo on the front of the United shirt for one match per season for both the men’s and women’s teams. (RED) was founded in 2006 by Bono, lead singer of the rock band U2, and attorney and activist Bobby Shriver to create products and experiences to help tackle global health crises.
