The Sun says they are trying to snatch Erding from under the noses of bitter rivals Newcastle United.
Black Cats boss Steve Bruce is eyeing up a £9million swoop for the Turkey hitman.
But Toon manager Alan Pardew said: "Erding has always been on our radar. He's a very good player and that is all I will say at the moment.
"We tried very hard on that one but we always knew there would be setbacks along the way."
