Harder-hitting admirers, however, have criticised his choice of gym area decor.Saliba is yet to sign a new dealBut fans have slammed his choice of posterSupporters think the gym could be a sign that William Saliba will stay at ArsenalSaliba hung a portrait of himself in the gym next to posters of basketball legends Dennis Rodman, Scottie Pippen, and Michael Jordan from the Chicago Bulls.But what truly enraged fans was the image of Tommy Shelby and Arthur from Peaky Blinders.Someone observed: “Glad he’s possibly staying but having Peaky Blinders posters on your walls holy cringe.”Another idea came from the Daily Star, which stated, “Love the bloke, but Peaky Blinders fetishisation is a sackable offence.”One more person said, “Get him sold.””He’s put a running machine in a shed,” one admirer added. I’m not sure if this indicates he intends to sign a new contract.”
