Speaking candidly in an interview with Betfred about Rashford’s struggles, Parker expressed disappointment over the England international’s apparent lack of consistency and leadership at a crucial stage in his career.
"Any other player, it would have been done and dusted by now," he said. "It’s been going on for too long. Most other players would have been put out of their misery and one of the saddest things in football is seeing talent go to waste because the player can’t be bothered. That’s what’s happening with Marcus Rashford."
He added: "He’s 27 now and you can’t keep switching it on and off. He can’t be called a kid. He’s supposed to be a mature player now that leads his teammates along the way, especially because he’s a local lad. If you ask him to lead the way, I believe three-year-olds wouldn’t even follow him at the moment. There’s nothing about him that suggests he wants to be a footballer and a Manchester United player."
