Luka Cveticanin is the player that everyone is talking about in Europe. Talk of him as the next Lazar Markovic/Radonjic type of player. Extremely fast. He's got better technique and is more of a dribbler than the two former players I mentioned. I remember watching a game live on youtube once and he absolutely demolished Zvezda by himself and this 03 Zvezda team is very good. It was really incredibly to watch. Capitalized on every opportunity he got (which wasn't many).
Only worry with him is that he will rely too much on his speed like Markovic or Radonjic. Radonjic had to learn the hard way and has developed a more complete game. Markovic never did. So, we will see how he develops over time. Currently the most talked about player of this generation.
The other big talent is Mateja Bacanin from Zvezda. Both Bacanin and Cveticanin were in the U17 team this year despite being a year younger. Don't have a video of Bacanin but have seen him in games many many times. Not just cause of his but the player most similar to his playing style is definitely Krasic. Krasic was quicker but Bacanin is a better finisher. Plays best when given freedom to roam in midfield. Very fast with the ball at his feet. Excellent technician. Best Zvezda has had in a long time. Love to dribble but much like Krasic in his CSKA days, Bacanin is sometimes too passive to take on his opponent. He prefers to shoot from long distance (which he is good at). Considered Zvezda's biggest talent at this level and has won many MVP awards for Serbia at youth level.
