West Ham United will reportedly need to pay €80m (£66m) if they wish to sign Sevilla forward Lucas Ocampos this summer.
The 27-year-old has been a key player for Julen Lopetegui's side this season, scoring eight goals and providing four assists in 35 appearances across all competitions.
According to Estadio Deportivo, Ocampos in close to extending his contract with Los Rojiblancos by a further year until June 2025, and his release clause is set to be increased from €70m to €80m.
The report adds that that Sevilla are confident they can keep hold of the Argentina international this summer, unless they fail to qualify for the Champions League.
Wolverhampton Wanderers have also been credited with an interest in signing Ocampos, but neither they or the Hammers are expected to match Sevilla's asking price.
West Ham are also understood to have identified the likes of Benfica's Darwin Nunez, Atalanta BC's Duvan Zapata and Leeds United's Raphinha as potential targets this summer.
