Paris Saint-Germain and Chelsea are among the clubs chasing Manchester United goalkeeper Dean Henderson, sources have told ESPN.

Henderson has emerged as one of the most promising young goalkeepers in the world after an impressive season on loan at Sheffield United.

The 22-year-old has a contract at Old Trafford until 2022 with the option of another 12 months, but his performances have alerted some of the biggest clubs in Europe.

Henderson is highly rated by United but is behind David de Gea and Sergio Romero in the pecking order and is unlikely to settle for a place on the bench after being No. 1 at Bramall Lane.

Sheffield United have the second best defensive record in the league behind only runaway leaders Liverpool as Chris Wilder's side have climbed to fifth in the table.

Henderson has kept nine clean sheets this season -- level with Liverpool goalkeeper Alisson -- to put himself in the running to be named the Premier League's best goalkeeper. His form has also alerted England manager Gareth Southgate ahead of this summer's European Championship.

United are keen to keep Henderson and have discussed the possibility of offering the former Carlisle youngster a new contract to reflect his rise in status.

But that has not put off PSG and Chelsea as they assess their goalkeeping situations ahead of the summer transfer window.

Chelsea spent £71.6 million on Kepa Arrizabalaga in 2018, but his form has become a concern for manager Frank Lampard and the 25-year-old was dropped for the 2-2 draw with Leicester in favour of 38-year-old Willy Caballero.
