Rashford joined Barcelona this summer after a challenging period at Old Trafford. He was loaned to Aston Villa for the second half of last season, where he scored four goals in 17 appearances. Barcelona's manager, Hansi Flick, was impressed by Rashford's performance and decided to bring him to the team.

Rashford has made appearances in friendly matches, including a debut against Vissel Kobe and a 45-minute match against FC Seoul. However, he has not been registered with the team yet, which may cause him to miss the opening game of the season.

Flick plans to use Rashford as a central striker in addition to his usual left-side position. However, Barcelona's inability to register several players due to salary relief issues may delay Flick's plan for Rashford.

Rashford's situation is one of several registration issues facing Barcelona. The team is working to resolve these issues as quickly as possible to ensure that all players are cleared to play in the upcoming season.
