Brazil international winger Osvaldo is reportedly a summer transfer target of Ukraine's Shakhtar Donetsk and Metalist Kharkiv.
The 26-year-old has been in impressive form for Brazilian club Sao Paulo and has twice been capped by Brazil coach Luiz Felipe Scolari this year, reports XInhua.
Sao Paulo have reportedly already received preliminary offers for Osvaldo from both clubs, considered two of Ukraine's top three alongside Dynamo Kiev.
Shakhtar already boast eight Brazilians in their squad and Metalist six.
Osvaldo, renowned for his speed and finishing ability, has scored eight goals from 24 appearances since joining Sao Paulo from Ceara in 2011.
