Bournemouth have rejected a bid in excess of £12 million from Sheffield United for goalkeeper Aaron Ramsdale.
The former England U21 international joined Bournemouth from United three years ago for £1m and was the club's stand-out performer, despite their relegation to the Championship.
The news suggests that England keeper Dean Henderson's stay in South Yorkshire is at an end after two successful loan spells at Bramall Lane.
Henderson is presently in negotiations over a new contract at Manchester United, but was expected to re-join Chris Wilder's side in time for the new season.
Bournemouth believe Ramsdale is at a similar stage in his career to Jordan Pickford when he joined Everton in 2017 for an initial £25m.
