Former Liverpool defender Stephen Warnock has questioned Dean Henderson's future at Manchester United.

Warnock is impressed by Henderson on-loan at Sheffield United.

He told the Daily Express: “He's a great goalkeeper.

“Sheffield United are really fortunate to have him and Billy Sharp scoring again.

“At one end, Sharpe is scoring. At the other, Henderson is saving shots that look destined for the top corner.

“Manchester United is a massive, massive step up though.

“Especially replacing David De Gea, who has probably been their best player in recent times.

“That would be a huge ask, to come in and straight into the first team.

“He [Henderson] has a really bright future though."
