Wolverhampton Wanderers have reportedly made a fresh approach for AEK Athens striker Nelson Oliveira.
The Premier League side were heavily linked with a move for the 29-year-old during the January transfer window, with reports claiming that they saw two bids turned down.
Greek outlet SDNA now reports that Wolves have revived their interest through agent Jorge Mendes, who has approached AEK over a possible deal.
However, AEK are understood to have given the latest offer short shrift as Wolves are still unwilling to increase their January bid of £3.6m.
Nuno Espirito Santo is in the market for a new striker in order to ease the goalscoring burden on first choice Raul Jimenez, who has been linked with a move away from Molineux this summer.
Oliveira scored 16 goals for AEK last season, including 14 in the league, and has previous experience in English football with Swansea City, Nottingham Forest, Norwich City and Reading.
