David Moyes will finally get a close up look at former Celtic goal machine Moussa Dembele.
West Ham face Dembele's side Lyon in an Europa League quarter-final first leg tie and Moyes has been strongly linked with a move for the striker in the last two transfer January windows.
The Frenchman is in red-hot form at the moment, boasting seven goals and two assists in his last 10 games across all competitions.
Manchester United, noted long-time admirers, are also reportedly monitoring Dembele and scouted him during their win against Porto.
The 25-year-old left Celtic in 2018 to join Lyon and his current deal runs out in 2023, which means Lyon risk losing him as a free agent if they cannot agree new terms before then.
As a result, Dembele may be available for as little as £20 million this summer if Lyon decide he is unlikely to extend his stay.
Celtic retain a significant sell-on fee for a player who became a smash hit in Glasgow's east end.
