The Tottenham youngster is inching closer to becoming a World Champion, after helping knock out White Hart Lane teammate Cameron Carter-Vickers' US side on Sunday.
And it was Veljkovic's Serbia who were victorious over the US, though the game went to penalties, with the two Spurs men failing to cover themselves with glory from the spot.
It was already sudden death by the time Carter Vickers took his penalty, and he showed why he wasn't in his country's initial five by blazing his effort over the bar. Veljkovic immediately followed, but although his effort was on target, it was saved by US goalkeeper Zack Steffen. Serbia went through in the next round of penalties when Nemanja Maksimovic converted.
It was the third clean sheet Serbia had kept in the competition, and with the 19-year-old starting in every one of his country's five games so far, it is clear Tottenham have a genuine talent on their hands, even if he does have to work on his spot kicks.
Veljkovic has already made his debut for Spurs, coming off the bench in the 2013-14 season's 5-1 demolition of Sunderland in the league. One further appearance came that season under Tim Sherwood, on the last day of the season against Aston Villa, while Mauricio Pochettino recognised the youngster by giving him a Europa League runout against AEL Limassol at the start of the season just gone.
The Swiss-born Serbian international spent two spells on loan at Championship clubs last year, struggling for game time at promotion chasing Middlesbrough, where he made 4 appearances, and then suffering injury at Charlton that restricted him to 3 outings.
But if he comes back to White Hart Lane as an Under-20 World Champion, don't be surprised if Pochettino fast tracks him to the first team squad that little bit quicker.
