Swansea City are considering an improved bid from Premier League newcomers Sheffield United for striker Oli McBurnie.
The latest offer from the Blades could result in a deal for the Scotland international that rises to £20m, BBC Wales Sport has learned.
Championship side Swansea have previously turned down bids from United, the last worth £15m.
McBurnie, 23, has not pushed to leave, but a move looks increasingly likely.
It is understood Swansea are "seriously considering" the latest offer, and believe the package could go a long way towards solving their remaining financial issues after relegation from the Premier League in 2018.
Head coach Steve Cooper admitted "anything is possible" regarding McBurnie following Saturday's 2-1 pre-season victory over Atalanta.
Losing McBurnie would leave the Championship club short of attacking options, with the transfer deadline looming on 8 August.
But if McBurnie moved before Saturday's Championship opener against Hull City, it would allow the Swans to look around for a possible replacement.
The club have also made no secret of their need to offload high wage earners - notably Andre Ayew, Borja Baston and Jefferson Montero.
