UEFA Euro 2020 has already given us a few young players to track, with Denmark's Mikkel Damsgaard, the Netherlands' Ryan Gravenberch and Italy's Manuel Locatelli all standing out.
However, some talented stars have been given limited minutes at Euro 2020 so far. Despite enjoying good seasons with their respective clubs, these players are yet to make their mark at the tournament.
With managers having the capacity to make five substitutions, these players should get their chance as Euro 2020 progresses. For now though, they are behind some big names in the pecking order.
We look at 5 stars who are yet to be unleashed at Euro 2020.
#5 Pedro Goncalves (Portugal)
Likened to fellow Portuguese midfielder Bruno Fernandes, Pedro Goncalves has slotted in perfectly at Sporting CP following the departure of his predecessor to Manchester United.
Nicknamed "Pote", Goncalves is seen as one of the best talents in Portuguese football, but he is yet to feature for Portugal at Euro 2020. The 22-year-old, who joined Sporting CP from Famalicao last summer, made 32 appearances in the league last season, scoring 23 goals and providing three assists as his club won the Primeira Liga.
Predominantly utilised as an attacking midfielder at Sporting CP, Pote can operate in a deeper midfield position as well as further forward. The likes of Fernandes and Renato Sanches are ahead of him in the pecking order at Euro 2020, and it is likely that Pote will have to wait patiently for his opportunity.
#4 Adama Traore (Spain)
Luis Enrique's Spain struggled during their first two group-stage games at Euro 2020, boasting incredible possession numbers but failing to break down their opposition. They drew against both Sweden and Poland, with technically gifted players like Koke, Rodri, Pedri and Dani Olmo struggling.
Adama Traore, renowned for his sensational dribbling ability and his pace, would surely have made an impact with his unpredictability on the wings.
Traore has been an important cog at Wolverhampton Wanderers, and has played on the wings and as a right wing-back. Spain enjoyed a wonderful performance against Slovakia, scoring five against them in their final Euro 2020 group-stage game. Traore made a cameo appearance in that game, but there is a feeling that the 25-year old could be used to devastating effect in the knockouts.
#3 Timo Werner (Germany)
Germany have not enjoyed a good Euro 2020 campaign so far. The Portugal performance was a big positive for manager Joachim Low, but Die Mannschaft produced two poor performances against France and Hungary in the group stages.
It has been surprising to see Chelsea star Timo Werner barely feature for his country at Euro 2020. The 25-year old endured a mixed debut season in the Premier League, but was a consistent starter for the Blues despite his struggles. For Germany, Werner has been reduced to a bench role.
Low has preferred to play Bayern Munich's Serge Gnabry up front, and Werner has made just two substitute appearances at Euro 2020 so far. Capable of playing on the left wing as well as a striker, it remains to be seen whether Low starts him against England.
#2 Jadon Sancho (England)
The coverage around England manager Gareth Southgate's reluctance to utilise Jadon Sancho at Euro 2020 has been well-documented.
Regarded as one of the best young players in world football, Sancho has been phenomenal since joining Borussia Dortmund in 2017. A highly creative, pacy winger, he has made just one substitute appearance so far at Euro 2020 despite England's attacking woes.
The 21-year old, who is closing in on a move to Manchester United, is clearly behind the likes of Jack Grealish, Phil Foden, Bukayo Saka and Marcus Rashford in the pecking order. It looks likely that Sancho's bench role will continue for the time being.
#1 Joao Felix (Portugal)
Where is Joao Felix? The talented young forward is yet to make an appearance for Portugal at Euro 2020.
Signed by Atletico Madrid from Benfica in 2019 for a club-record fee of £114.5 million, Felix has not been a consistent performer for the Spanish giants. Despite that, his talent is unquestionable, and the fact that Portugal manager Fernando Santos has refrained from using him at Euro 2020 is surprising.
Felix was not even on the bench for the game against Germany, with an injury cited as the reason. With players like Bruno Fernandes, Bernardo Silva and Diogo Jota not at their very best, Felix could prove to be key for Portugal in the latter stages of Euro 2020.
