Manchester United star Alejandro Garnacho has prompted the ire of the club's supporters by wearing another Premier League side's shirt. The winger posted a picture of himself wearing an Aston Villa top with 'Rashford' on the back. Both Garnacho and Marcus Rashford are expected to leave Manchester this summer, and neither is part of Ruben Amorim's plans at Old Trafford . Rashford spent the second half of last season on loan at Villa Park after being left out of numerous United squads. And Argentina international Garnacho was told to find a new club at the end of the season after venting his frustration at not starting in the Europa League final. The 20-year-old was left out of United's final Premier League matchday squad. The young star was the subject of interest in January as Napoli had a bid in the region of £40million turned down . An asking price of £70m was initially touted for Garnacho but it has since been suggested that figure could be slashed to facilitate a move. And Garnacho's social media activity appears to have signalled some camaraderie with Rashford, to the dismay of some United fans. Sharing photographs from his holiday to Ibiza, one included a picture of him wearing Marcus Rashford's Aston Villa shirt. Rashford responded to the post with the words 'My brother' and a heart emoji. Others of a United persuasion were less kind, however. "To wear another Premier club's top is madness and proves you clearly are not mentally ready for the next level," wrote one fan. "You've lost the respect of majority of United fans especially those that have backed you," added another. "Garnacho just keeps proving why he must leave," remarked a supporter. "His ego is ridiculous for somebody with his ability." "There's a line and you just crossed it," said another. "See ya later Garnacho, clear off and find yourself another club," said a further fan. An additional supporter suggested the image was an intentional move. "Garnacho knows exactly what he’s doing wearing that jersey.. weirdo," they said. Both players could soon find themselves returning to United however. Rashford is said to be ready to return for pre-season training if a transfer away does not materialise . Nobody is currently in serious talks to sign the 27-year-old and Rashford is 'preparing' for such an eventuality with United's stars due back for tests and training next month. Despite interest from a host of Europe's elite , such as Barcelona , Bayern Munich , Inter Milan and Juventus , United are believed to have not received any formal offers for the forward.
