Newcastle United boss Eddie Howe is unsure about keeping hold of Lewis Hall.
The young wing-back is on-loan to June from Chelsea without a purchase option.
Howe said: "You are probably asking the wrong person. I'm not one hundred percent sure.
"Right now he is here, he is a Newcastle player. But I think there are certain criteria he has to meet.
"Lewis is a very talented player. He has great technical qualities. He is creative and is skilled with the decisive pass.
"He has certain things to learn defensively, which we are working on. But he is young, and has recently been retrained as a left back. It takes some time to get into that position."
