Team-mates in our Under-21s last season - although Milos spent most of the season out on loan - the pair line-up for the USA and Serbia respectively in the quarter-final clash in Auckland, New Zealand. The game kicks-off at 4.30pm local time, 4.30am UK.
Cameron, an Academy first year last season and still just 17 and Milos, 19, have played every minute for their respective countries so far.
Both had thrilling last 16 matches to get to this point - Serbia found an equaliser against Hungary in the 91st minute before winning two minutes before the end of extra time while Cameron had to help USA defend stoutly with 10 men for the final stages against Colombia, who also had a penalty saved.
The pair are full of respect for each other going into the clash. "Cameron is a very good player, a big talent, I really believe he has the potential to go all the way and play for the first team at Spurs, everyone rates him highly," said Milos, who had loan spells at Middlesbrough and Charlton last season.
"He’s so strong for his age, he’s two years younger than me but here he is playing in the Under-20 World Cup and that’s huge for his development."
Cameron returned the compliment. "Milos is such a good player, calm and composed on the ball and defensively, he reads the game really well. He always seems to be in the right position.
"I haven’t had the chance to play many matches with him because he’s been out on loan and then injured but in training, you can really see his quality, one and two-touch passing and he can play centre-back or holding midfield, that says a lot about how good he is on the ball.
"It will be weird to see him lining-up in the tunnel! We’ll both go out determined to win. It will be interesting to see him before and after the game. I’m just hoping we can win!"
