Nigeria midfielder Michael Babatunde has urged Sunderland to step up their interest in him.
The 21-year-old, who made two appearances for his country at the World Cup in Brazil, has claimed the Black Cats have made him an offer and has indicated is interested in the proposition of continuing his career in the Barclays Premier League.
Babatunde, who plays his club football in Ukraine with Volyn Lutsk, told www.sl10.ng: " I have received several offers from different places, but I'm interested in the one from Sunderland.
"They have contacted my agent, and we will see how it goes from there.
"There are about two offers from clubs in Turkey as well, which are both under consideration and will be discussed at the right time."
