Manchester United have put in a £50 million bid for Frenkie de Jong.

The Dutch midfielder is emerging as new manager Erik ten Hag's ideal candidate to replace the departing Paul Pogba.

According to The Sun, United are testing Barcelona's resolve over de Jong.

While the midfielder is not keen to leave the Catalan club, they are in financial distress, and may have no option buy to cash in on him.

Barcelona are presently unable to register new players, as they are not in compliance with La Liga Financial Fair Play rules.

French midfielder Pogba is set to re-join Juventus on a free transfer from United for the second time in his career.
