It's worth noting that both Garnacho and Rashford are set to leave Manchester United this summer. Garnacho's manager, Ruben Amorim, had told him earlier that he needs to find a new club, and Rashford is hoping to secure a move to Barcelona. Other clubs, such as Napoli and Chelsea, are also interested in signing Garnacho.

Despite the mixed reactions from United fans, Rashford has shown his support for Garnacho by responding to his post with a simple "my brother". Garnacho has had a successful time at Manchester United, scoring 26 goals and providing 22 assists in 144 appearances, and winning an FA Cup and a Carabao Cup.

As Garnacho seeks a new club, he may face his old team in the future. With several clubs interested in signing him, his future is looking uncertain, but he has the support of his teammates, including Rashford.

Garnacho's brother, Roberto, had previously accused manager Amorim of "throwing him under the bus" after a game against Tottenham. However, it seems that Garnacho has moved on from the incident and is focused on finding a new club.

Overall, Garnacho's decision to wear a Villa shirt with Rashford's name on the back has sparked a mixed reaction from United fans. While some have asked him to leave the club, others have shown their support for him.
