The striker has been a success on-loan from West Brom.
"I will see what he is saying, I talk with him every day," the Newcastle manager said. "Everybody is really pleased because he has played really well for us, he was a key player in our achievements.
“It's very easy to say we have to sign him, but still we have to decide what is going on with me. Obviously he has to wait and see what happens with West Bromich Albion so all these things will have to wait a couple of weeks and after that we will know.
“I understand you have to ask and I will say the same to all the fans but we have to wait and in 10 days we will know what's going on. With me, it's just common sense because with another manager he might want to change Salomon Rondon, so it depends on these things and after you can move forward."
