Chris Hughton hit back by saying the player has yet to settle on Tyneside and he doesn't want to put too much pressure on him.
Personally, I believe if the player was fit enough to play the last 20 minutes what difference does it matter when he was introduced?
20 minutes, 45 or 90? If he plays - he plays.
Chris Hughton: "There's no doubt he's got ability, we knew that before he came.
"But he's feeling his way in.
"The language can be a little bit of a problem and getting used to the tempo of the Premier League.
"These are all factors. There's no doubt he has ability and I'm quite sure we'll be seeing a lot more of him."
