West Ham and Burnley will compete for the signing of Hull City top scorer Robert Snodgrass after the Hammers had a bid accepted.
Burnley had an offer accepted on Wednesday and, while both are believed to be in the region of £10m, West Ham's is higher.
The Tigers, who are 19th in the Premier League, rejected a bid from the Hammers earlier this month.
The Scotland midfielder, 29, has scored seven Premier League goals this season.
The Tigers say the move is now down to the player and he has not yet gone for a medical at Burnley.
