West Ham are interested in signing West Brom forward Salomon Rondon at the end of the season.
According to The Telegraph, Rondon has a clause in his contract allowing him to leave if a club pays £16.5m.
However, this only becomes active if West Brom are relegated to the Championship, which is likely to be confirmed in the coming weeks.
This will mean that if West Ham can match the price, they will face no opposition from West Brom looking to keep him.
The report does not, however, mention whether or not they would be willing to match his release clause.
West Brom previously rejected a massive bid from Chinese side Tianjin Quanjian last season, when they offered £30m in January 2017.
Rondon has scored six and assisted three in the Premier League this season, after scoring eight and assisting two last term.
West Ham are looking to add another striker ahead of next season after struggling to find a consistent scorer.
