Despite limited opportunities in the 2017-18 season, the 22-year-old scored 11 goals across all competitions as Madrid claimed their third straight Champions League crown.

KYLIAN MBAPPE (FRANCE)

Kylian Mbappe announced himself during Monaco's 2016-17 Champions League run, which ended with a 4-1 aggregate loss to Juventus in the semifinals.

After scoring 26 goals in all competitions in his first full season, the then-18-year-old joined Paris Saint-Germain last August in a deal ultimately worth 180 million euros.

And he didn't disappoint during his first season in the French capital, netting 21 times in 44 matches across all competitions.

He looks likely to start for Les Bleus, either as part of a two-man strike-force with Olivier Giroud or alongside Antoine Griezmann, slightly behind the Chelsea target man.

DANIEL ARZANI (AUSTRALIA)

Australia winger Daniel Arzani is the youngest player in the World Cup and is the only man among the 32 teams born in 1999.

The 19-year-old has had a rapid rise to football's top level, having only made his professional debut for Melbourne City last August.

He has since started just 16 times for the A-League club but showed enough during the season to earn a place in coach Bert van Marwijk's squad for Russia.

Arzani is already vindicating his surprise inclusion, scoring on his debut in Australia's 4-0 friendly win over the Czech Republic on June 1.
