West Ham are in talks with Ajax midfielder Mohammed Kudus over a big-money move to London Stadium.
The 23-year-old scored a hat-trick in Ajax's Europa League play-off win over Ludogorets in Bulgaria on Thursday.
The Hammers were represented at the game, with the Ghana international saying afterwards it might have been his last match for the Dutch side.
Kudus has been the subject of huge interest from Premier League clubs this summer.
Brighton were understood to have reached an agreement with Ajax for Kudus earlier this month, but they were unable to finalise personal terms.
