Islam Slimani was unveiled on the eve of the Man United game, but he didn't play because of injury.
However the Algeria international said he would be "very happy" to win a permanent deal at Newcastle.
Asked if he was open to staying at the club beyond this season, Slimani said: “Yes, yes. I’m just on loan at the minute, but if I could stay here I’d be very happy, so let’s see how it goes.”
