Manchester United are reportedly looking into a move for Burnley goalkeeper Nick Pope during the summer transfer window.
Henderson has been the deputy to the Spaniard this term, but the hierarchy believe he does not have sufficient Premier League experience.
According to The Mail, Pope is one of the players on their radar following a top season for the Clarets, where he has kept nine clean sheets.
The England international has been tipped to secure a big-club move and the Red Devils have him as an option to replace De Gea.
The Clarets are likely to demand as much as £50m to part ways with the shot-stopper, who has made exactly 101 Premier League appearances.
