Major tournaments can be breakthrough occasions for young players, and Euro 2016 is packed with talent just waiting to announce themselves on the international stage.
But will it be Dele Alli or Divock Origi stealing the show for their respective teams this summer?Here we pick out 10 young players capable of making a big impression in France this summer...
Alli's first season in the Premier League was a successful one with Tottenham
Dele Alli (England)
Alli registered 10 goals and nine assists in a brilliant breakthrough season with Tottenham, and England are optimistic that he could have a similar impact at Euro 2016.
Alli scored on his first start for the Three Lions against France in November, and there was another starring performance in the 3-2 win over Germany in March.
Just over a year on from turning out for MK Dons in League One, the 20-year-old is expected to play a key role for Roy Hodgson's side in his first international tournament.
France winger Kingsley Coman has excited for Bayern Munich this season
Kingsley Coman (France)
Pep Guardiola described Kingsley Coman as "insanely good" during his impressive campaign for Bayern Munich last season. The 19-year-old Frenchman notched four goals and six assists in 23 Bundesliga appearances, and he also starred in the Champions League, playing a key role in Bayern's 4-2 win over Juventus in the last 16. Coman scored his first goal for France in a 4-2 win over Russia in March, and he is likely to get more opportunities at the Euros.
Switzerland's Breel Embolo in action
Breel Embolo (Switzerland)
Swiss striker Embolo is one to watch in Group A. The striker only turned 19 in February but he has already scored 30 goals in 86 appearances for Basel, he has featured in the Champions League and he has netted once in nine appearances for Switzerland. Tottenham are believed to be interested, and newspaper reports say he has also been scouted by Manchester United and Bayern Munich.
Russia midfielder Aleksandr Golovin is highly rated by manager Leonid Slutsky
Aleksandr Golovin (Russia)
"He can really become a high-level player." That was Russia manager Leonid Slutsky's verdict on Golovin when he named his squad for Euro 2016.
The highly-rated playmaker, 20, will be their only player under the age of 25 in France. Although not yet a regular starter for CSKA Moscow in the Russian Premier League, he has scored two goals in three appearances for his country.
He will be hoping to feature against England on June 11.
Anthony Martial will be hoping to build on a fine season with Manchester United
Anthony Martial (France)
Martial defied his doubters with an impressive debut campaign at Manchester United following his record-breaking transfer from Monaco.
His performances were a rare bright spot in a disappointing season at Old Trafford, and he broke into France's senior squad in August. He is yet to score in eight appearances for Didier Deschamps' side, but he is likely to feature prominently when the tournament gets started.
Divock Origi will look to take his fine form with Liverpool into Euro 2016
Divock Origi (Belgium)
Origi has already made an impact on an international tournament with his late winner against Russia at the 2014 World Cup, but this could be a bigger opportunity for the versatile 21-year-old forward.
The Liverpool youngster finished the season with five goals in his last six games including a derby strike against Everton, so he is in the sort of form that could see him seize the moment if Belgium's array of forwards fail to fire.
Marcus Rashford is the surprise inclusion in England's Euro 2016 squad
Marcus Rashford (England)
The Manchester United forward had not even made his professional debut as recently as February, but the 18-year-old forced his way into England's plans by making an instant impact at Old Trafford.
After scoring twice on his United debut against Midtjylland he also found the net on his first Premier League bow. Another goal-scoring debut came for England against Australia in May. Could he now be the wildcard option from the bench?
Renato Sanches will complete his transfer to Bayern Munich this summer
Renato Sanches (Portugal)
Sanches' switch from Benfica to Bayern Munich will officially go through during the tournament, underlining his status as one of the most promising young players in Europe.
The 18-year-old made his breakthrough with the Benfica first-team in October and made his international debut in March.
He's the youngest player to feature in a tournament squad for Portugal since Cristiano Ronaldo's selection for Euro 2004 - can he make a similar impact?
Schalke's Leroy Sane offers pace and quality for Jogi Low's Germany
Leroy Sane (Germany)
Germany have introduced some young blood into their squad of World Cup winners and the pace of Sane on the right flank could prove a useful weapon in France.
The Schalke winger broke through into his club's first-team last season - even scoring away to Real Madrid - and has further enhanced his reputation in the 2015/16 campaign. Having made his international debut against France in November, he's in the 23 and just waiting for a chance.
Dortmund's Julian Weigl has broken into Germany's squad in the nick of time
Julian Weigl (Germany)
Weigl was part of the 1860 Munich side that finished in the bottom three of the second tier of German football in 2014/15, but his stock has risen dramatically in the past 12 months.
The 20-year-old has impressed in a holding role for Thomas Tuchel's Borussia Dortmund and graduated to international level with a debut against Slovakia in May.
A composed presence, don't be surprised if he fits in seamlessly should Jogi Low rotate his squad.
