Manchester United have reportedly placed a £20m valuation on English goalkeeper Dean Henderson.

The 22-year-old, who is yet to make a first-team appearance for the Red Devils, is currently in his second season on loan with Sheffield United.

The stopper made a glaring error in Liverpool's 1-0 win at Bramall Lane on Saturday afternoon - allowing a strike from Georginio Wijnaldum to squeeze into the back of the net.

The England Under-21 international has largely impressed with the Blades, though, with his form last season helping Chris Wilder's side earn promotion from the Championship.

Despite being highly rated by his parent club, Henderson's path into the first team is blocked by David de Gea, who recently signed a new long-term contract at Old Trafford.

According to The Sun, United will therefore make Henderson available for transfer at the end of the 2019-20 campaign, and the 20-time English champions would want a transfer fee of around £20m.

Experienced Argentina international Sergio Romero is currently United's number two goalkeeper while 36-year-old Lee Grant is third choice at the club.
