AEK Athens are frustrated with Wolves’ approaches for Nelson Oliveira after rejecting a second bid for the striker.
The Greek side feel Wolves have tried to get Oliveira on the cheap, having failed to match his 6.5million euros release clause, the PA news agency understands.

He has scored nine goals in 20 games, with AEK third in the Greek Super League.
