Former England star, Danny Mills, has warned Manchester United manager, Ole Gunnar Solskjaer, over his plans to convert Jadon Sancho from a winger into a wing-back, saying it “almost a sackable offence”.

Sancho has failed to score or provide an assist in 13 appearances across all competitions for the Red Devils since his £73million move from Borussia Dortmund.

According to The Athletic, Solskjaer has reacted to the dip in form by trying the 21-year-old out as a right wing-back in training.

United have played a 3-4-1-2 formation in the past three matches after being thrashed 5-0 by Liverpool and the report states Solskjaer may field Sancho at right wing-back ahead of Aaron Wan-Bissaka against certain opponents.

Former England right-back Mills has branded the move “ridiculous” and believes Solskjaer should develop a system which suits his big-money summer signing instead of trying to force square pegs into round holes.

“Good luck turning him into a wing-back,” Mills told Football Insider .

“He didn’t play for England too much in the Euros because I don’t think he was reliable enough to track back and do the defensive side of it. Dortmund never played him there.

“You bought a winger who is going to create chances and score goals. Suddenly you’re going to play him at wing-back in an unbelievably leaky defence. It’s like, really?

“That’s almost a sackable offence in itself.

“Shall we put Cristiano Ronaldo at centre-half because he can head a ball? I think Ronaldo can head the ball better than the centre-halves at the moment so should they put him at centre-half?

“It’s more than a little bit ridiculous.”
