Wickham leads the line for the Black Cats, but has failed to hit the back of the net in the league so far this season.
However, Poyet feels that his main striker is still playing better than he was last season and the Uruguayan insists that he enjoys watching the England youth-international play.
“He has been impressive and he has been a massive player for us," he said to the Shields Gazette.
“I enjoy watching him and I just want to start seeing him put the ball in the net.”
Wickham played a major role in keeping Sunderland in the Premier League towards the back end of last season, but he has struggled to maintain that form since.
The target-man hit a purple patch at the right time for the Wearside club, as they performed a miraculous escape from danger.
He was expected to rekindle those sort of performances at the start of this year, but his touch in-front of goal seems to have left him.
Sunderland have become the Premier League's draw specialists and they are still looking for their first win of the season.
Part of this has been down to their lack of attacking threat and the club will be relying on Wickham to start hitting the back of the net soon.
It seems that Poyet has identified the 21-year-old as the man who he wants to be the focal point of the Black Cats' attack and that role carries a responsibility.
If he does want to keep it, Wickham will need to start getting on the scoresheet sooner rather than later and a game against Stoke City provides him with the chance to do just that.
