Steve Bruce admits Allan Saint-Maximin can be 'difficult' to manage at times but is convinced the 'sky is the limit' for the French winger.
The 23-year-old committed his future to Newcastle United on Wednesday evening after penning a new six-year deal on Tyneside.
It was reward for an exciting debut campaign at St James' Park and Bruce was well aware the former Nice star was 'different' when he first stepped on to the training pitch.
But amid all of his exuberance, Saint-Maximin is also a student of the game and Bruce is convinced he will go right to the top of the game.
"He is different. We all know that," Bruce told NUFC TV.
"But there's no question about one thing. He enjoys his football like nobody else. If you ask him the result of any game over the weekend, he will tell you the result, the goalscorer, and where they are, whether it is in France, Italy, Germany.
"He loves football and, of course, I have to manage him, and there are times, I am not going to not tell the truth and say he isn't difficult at times.
"However, he is worth it. That is what management is all about. He tests you to the limit at times but when he is right, he is a good player and he is worth his weight in gold to all of us.
"I said from day one that when he walks through the door and the supporters see him they will enjoy seeing him.
"That goes for Newcastle fans but it also goes for fans up and down the country. The one person they all ask about is Saint-Maximin.
"He is a talent, the kid, and I hope now he goes and produces what he is capable of producing.
"The sky's the limit for him."
