Marcus Rashford 'shouldn't play for England' with Man Utd star brutally torn apart

However, Rashford has toiled this term with the United star netting just once from six appearances.

His downturn in form has coincided with the club enduring their worst start to a season since 1986.

And Parker, speaking to MyBettingSites.co.uk, believes Rashford shouldn't play for England amid his poor form.

“Rashford is an England international. Should he be that? No, but that's what he is so he is a key player for this club, which creates high expectations from the fans," he said.

"They want to see more from him.

“Ryan Giggs and Lee Sharpe played on the right wing when I played at the club. They were 100 times better than Rashford.

"Did they score as many goals in one season as Rashford? No, but did they produce more than Rashford? Yes, they created chances, made the runs and they were not selfish at all.

“Rashford has openly admitted that he can´t play in the middle.

"That's why he can only play at the wing but in my opinion he never gave it a shot.

"He was given the opportunity to be a real striker and he didn't grab it.”

Parker continued his astonishing attack on Rashford by saying the United star hasn't lived up to his earlier potential.

The forward burst onto the scene in 2016, quickly establishing himself as a household name.

But consistency has always been an issue for Rashford, who has often blown hot and cold over the course of his career.

Parker added: “I was criticising Rashford when he scored goals because I wanted him to provide more for the team.

"Now, he is not scoring goals anymore and his decision making is still poor.

“Everyone was saying that he was winning Man United games but the only thing they could come up with is that he was scoring goals.

“It has taken people a while but now they are finally seeing that he is not contributing with anything.

"He should be because he is a fast winger with decent technical abilities, but in fact he is just a selfish player who lives on the back of being good in February.

“I think that Man United rushed in too quickly to give him this huge contract.

"Overall he has been delivering a poor return throughout his Man United career. That´s a fact.”

Rashford is expected to start for United when they face Burnley on Saturday night (8pm) as the club look to return to winning ways after a 4-3 defeat to Bayern Munich in midweek.
