Denmark U17 coach Jesper Mikkelsen isn't surprised by the progress of Chidozie Obi-Martin.
The 15 year-old striker made his debut in yesterday's UEFA Youth League defeat at Sevilla.
Mikkelsen told Bold: "When you look at 'Chido', he doesn't look like someone who hasn't turned 16 yet. First of all, he has a physique that is really advantageous as a football player.
"He is big and strong, but he is also reasonably agile. He is good at sticking to the game, but he is actually also good at challenging and dribbling himself.
"So of course that makes him interesting now here and in the long run, because it is interesting to see how much this physique can carry him forward towards a breakthrough on the big stage."
But there are also several areas that Obi-Martin must work on in order to utilize his great potential.
"Right now he is really dominant because of his physique, but I don't think that is the only reason.
"His greatest characteristic and challenge is that he really wants to score goals. When I say it can also be a disadvantage, I mean that he can sometimes play his own game.
"He is very searching for chances, where he forgets that you also have to play with the others."
