West Ham have asked about Brazilian defender Vitao who is on loan at Internacional from Shakhtar Donetsk.
The Hammers are trying to make early headway in the market for new boss Julen Lopetegui.
Vitao has made three appearances from Internacional’s seven league matches in the Brazilian league so far.
The 24-year old is also a target for Villarreal, who missed on on a European spot after finishing eighth in LaLiga.
West Ham saw a deal for Flamengo’s Fabrizio Bruno falter over personal terms last week.

The Hammers have made progress with Palmeiras over a £25m deal for winger Luis Guilherme
Talks are progressing well over a £25.5m deal for Palmeiras winger Luis Guilherme.
The East London club are undergoing a change this summer, after the exit of David Moyes as manager, and the incoming management of Lopetegui.
West Ham finished ninth last season, missing out on European football, despite reaching the Europa League quarter-finals this term, and winning the Europa Conference League 12 months ago.
