Newcastle boss Alan Pardew is convinced there is more to come from striker Luuk de Jong even though he is yet to score for the club.
The 23-year-old Dutchman joined the Magpies on loan from German side Borussia Monchengladbach in January having not started a single game this season at that point and without a goal in club football since April 6.
De Jong has been unable to end his personal drought after eight appearances for Newcastle but Pardew hopes the player will convince him that he can have a long-term future on Tyneside.
Pardew said: "It's important that his all-round game improves from where he is right now, but that will come with confidence and I can see him growing every day here.
"I know he likes the environment that he has found himself in, and players flourish when they start enjoying their football. Hopefully he can start doing that again because he had a tough time in Germany.
"I am trying to introduce him, trying to give him games where I think he can regain his confidence.
"He has had some good displays for us, but there is more to come and I hope between now and the end of the year, he shows that to our fans because we know at this club that we need strikers, and I am hoping he can tick a box for us between now and the end."
Former FC Twente striker De Jong's next chance to impress could come at Southampton on Saturday with leading scorer Loic Remy missing once again with the calf injury which has forced him to sit out the last three games, although he is scheduled to return to full training on Monday.
However, full-back Mathieu Debuchy is unlikely to join him for some time yet with his groin problem ongoing.
Pardew said: "We think Remy will train on Monday. He is going to training over the weekend, so he has got a good chance for Manchester United.
"Mathieu, we think, will be a bit longer than that, maybe another couple of weeks."
