Manchester United may have to go to £40m this afternoon to convince Bournemouth to sell Josh King.
Sky Sports says United are considering a second bid for King after their first offer of around £20m was rejected.
United are keen to sign a new striker before Friday's transfer deadline and it is understood manager Ole Gunnar Solskjaer is looking at the Norway international as a possible replacement for the injured Marcus Rashford.
The 28-year-old has established himself at Bournemouth in the Premier League, scoring 45 goals in 151 appearances.
If United were to sign King, Blackburn have a sell-on percentage of any deal, which is thought to be around 20 per cent.
Despite their ongoing search for a new striker, United have turned down the chance to sign Real Sociedad forward Willian Jose.
Cherries boss Eddie Howe said this morning: "It's a difficult question for me to answer because a lot of these things are out of my control. It's not my call. It's for the chief executive and the owner. All I can say is that I love Josh as a player and a person. I understand his position. I know what Manchester United means to him so let's wait and see."
