There is a 'breakout star' in every major international event - an undiscovered prodigy who makes a name for himself and wins a hefty transfer.
At the 2014 World Cup, James Rodriguez was the man of the moment, Renato Sanches lit up Europe two years later, and Benjamin Pavard was the unexpected star of Russia 2018. Who can forget England's own Wayne Rooney, who made his debut in 2004?
It's still unclear who will be permanently connected with Euro 2020, but there is already a slew of rising stars competing for that honor - and a blockbuster move.
With the knockout stages underway, Aptweve takes a look at some of the lesser-known players that are most likely to make a massive move after Euro 2020 concludes next month.
MIKKEL DAMSGAARD (Denmark)
Current club: Sampdoria
Mikkel Damsgaard wasn't supposed to be such a big part of Denmark's Euro 2020 squad.
Following Christian Eriksen's heart attack and shock collapse in Denmark's opening game of the tournament against Finland, the midfielder was only recently inserted into the starting lineup.
Damsgaard has continued to excel since then. The 20-year-old was a constant threat on the counterattack in Denmark's second encounter against Belgium and was unlucky not to score in the first half.
The midfielder made up for it in an emphatic manner in Denmark's last group game against Russia, scoring a miracle goal from the edge of the area in a 4-1 win that advanced them to the knockout stages.
Damsgaard impressed fans at Sampdoria last season, as Serie A fans will recall. Last season, the 20-year-old was a constant presence for the Italian side, scoring two goals and providing four assists.
Barcelona is reportedly interested in signing the Danish midfielder once Euro 2020 concludes, but Sampdoria hopes to spark a bidding war between the Catalans, Juventus, and Tottenham.
Following Damsgaard's heroics in Denmark, Sampdoria president Massimo Ferrero announced this week that he had set a £27 million price tag on him but will raise it if he continues to score.
'I'll tell you, it's a reasonable price, today at least €30 million,' Ferrero told Il Secolo XIX. But if he scores again, he'll be worth €40 million.'
ALEXANDER ISAK (Sweden)
Current club: Real Sociedad
By filling the void left by Zlatan Ibrahimovic's injury, Sweden striker Alexander Isak has already grabbed a lead in the battle to be the 'breakout star' at Euro 2020.
Despite not scoring, the 21-year-old attacker wore down Spain's defense in the first encounter before helping Sweden defeat Slovakia.
Isak made an excellent pass to Robin Quaison, who was awarded a penalty by Martin Dubravka, which Emil Forsberg converted. Several pundits remarked on the young striker's blistering pace and excellent close control throughout the match against Slovakia.
'Don't believe there's much doubt that Alexander Isak will receive a lot of attention from clubs around Europe,' Match of the Day host Gary Lineker tweeted. 'Extremely gifted.'
Isak has a £59 million release clause, but his current club, Real Sociedad, wants to extend his contract, bringing the total pay-out to £76 million.
Real Madrid is interested in Isak's services as a back-up to Karim Benzema, according to Spanish news site AS, and Florentino Perez believes that having a solid relationship with his agency - who also represent Luka Modric - will help in discussions.
Real would join Arsenal, a long-time admirer, at the negotiating table. Speaking on the Arsenal ties, Micah Richards stated that he would love to see Isak play in the Premier League next season.
'He's got such quick feet for a huge man,' he told the BBC after the Slovakia encounter. This man, if there was anyone who could make a difference in this game, it was him.
'He can accomplish it in the Premier League.' I'd like to see him in the Premier League; he's been associated with Arsenal so that I could have stumbled upon a hidden gem.'
MANUEL LOCATELLI (Italy)
Current club: Sassuolo
When Marco Verratti was injured for the first two Euro 2020 group games, Italy was apprehensive, but Manuel Locatelli stepped up to calm the concerns.
The 23-year-old was picked in Roberto Mancini's starting lineup for the Azzurri's 3-0 victories over Turkey and Switzerland in their first matches.
Locatelli shone in an Italy uniform for the first time in the second game against Switzerland, scoring two excellent goals on the break that drew comparisons to Marco Tardelli's shot and goal celebration.
The midfielder is fresh off a great season with Sassuolo, who finished seventh in Serie A under Roberto de Zerbi, and his Euro 2020 performances thus far have proved that he is ready for a step up this summer.
Juventus are presently the frontrunners for Locatelli, with newly-appointed head coach Max Allegri having previously worked with the player.
Allegri was in charge of AC Milan when Locatelli initially joined the first squad. Sources indicate the Old Lady is willing to pay £26 million-plus young defender Radu Dragusin for the midfielder's services.
However, according to rumors in Italy, Borussia Dortmund and Arsenal have made formal offers to Sassuolo for Locatelli, so this may be an exciting transfer tale.
DONYELL MALEN (Netherlands)
Current club: PSV Eindhoven
Donyell Malen, a Dutch striker, emerged onto the scene in Holland's last group encounter against North Macedonia, playing a pivotal role in two of Frank de Boer's side's goals.
Throughout the afternoon, the 22-year-old was a constant thorn in the Macedonian defense, displaying several changes of pace to unleash deadly counterattacks.
He started the breakaway and provided an assist for Memphis Depay's opener before using cute skill to play in Gini Wijnaldum, who scored the second goal.
Malen also scored 27 goals and added ten assists for PSV last season, making him one of Europe's best young attackers.
Arsenal let the striker go when he was young, and the Gunners have been linked with a reunion with the Dutch striker.
However, according to rumors in Germany, Liverpool is interested in signing Malen as an attacking option for next season, with sporting director Michael Edwards ready to start talks with PSV.
However, it remains to be seen whether his glaring miss when one-on-one with the goalie in the Czech Republic's last-16 setback deters any of those suitors.
