West Ham loan Nikola Vlasic has an agreement with Torino FC should his club decide to activate the clause.
The 25-year-old is enjoying a good loan spell in Serie A and is interested in continuing with his new club beyond this season.
While on loan at Italian Serie A side Torino this season, Nikola Vlasic has made quite an impact after scoring just one goal in 36 appearances for West Ham United last season.
The man on loan from West Ham has scored in three consecutive games against Cremonese, Atalanta and Lecce and has a total of four goals and two assists so far.
Il Toro, as he is known in Italy, has a €14.5m purchase option at the end of the season that could activate Torino.
