According to The Sun, West Ham United must part with £25 million if they want Blackburn Rovers striker Adam Armstrong this summer.
Manager David Moyes has personally kept tabs on the Newcastle United academy graduate as he looks to replace Sebastien Haller ahead of next season.
The Ivory Coast international striker was sold to Ajax last month, but the Hammers could not get a replacement before the transfer window shut and will end the campaign with Michail Antonio as their only natural number 9.
Armstrong has bagged 20 goals and three assists in 34 games across all competitions so far this term, but Rovers are 12 points off the promotion play-offs spots and could be forced to cash in on him in the coming months.
