UEFA.com shines a light on the players with a century of international appearances who could be set to grace the tournament this summer.
176 caps: Cristiano Ronaldo (Portugal)
A Portugal debutant in 2003, Ronaldo shows no signs of slowing down. Despite being injured in the final, winning UEFA EURO 2016 was the forward's pinnacle with the national team – who can forget his efforts from the touchline that Paris night? He has moved beyond a century of Portugal goals and is closing on Ali Daei's all-time international record.
138 caps: Luka Modrić (Croatia)
Oozing class from every pore, Modrić's annus mirabilis came in 2018 when he helped Croatia to the World Cup final, picked up that tournament's Golden Ball award and was later named UEFA Men's Player of the Year.
132 caps: João Moutinho (Portugal)
Moutinho has quietly been doing his thing for Portugal since 2005. As tenacious as he is creative, the midfielder remains a key cog in Fernando Santos's set-up even at the advanced age of 34.
130 caps: Sebastian Larsson (Sweden)
Compatriot Zlatan Ibrahimović has more often than not stolen the headlines during the past decade or so, but midfielder and set-piece expert Larsson has proven a model of consistency for his country.

127 caps: Jan Vertonghen (Belgium)
A steadying influence who arrived on the scene while Belgium were still struggling to qualify for major tournaments, the Benfica defender has been a mainstay throughout the rise of his country's golden generation.
127 caps: Marek Hamšík (Slovakia)
Now plying his trade in Sweden after a spell in China, the 33-year-old amassed more than 500 appearances and scored 121 goals in 11 full seasons with Napoli. He still stands as his country's talisman and captain.
126 caps: Hugo Lloris (France)
Lloris has been Les Bleus' permanent captain since before EURO 2012; he came so close to leading them to glory on home soil five years ago, but more than made amends in Russia in 2018.
122 caps: Sergio Busquets (Spain)
Midfielder Busquets emerged soon after La Roja's EURO 2008 triumph and has been one of the first names on the team sheet ever since. A player who has redefined his position and whose qualities every side craves.
121 caps: Goran Pandev (North Macedonia)
For so long his country's star attraction, Pandev's career looks to be reaching a fairy-tale crescendo as he contests his first major tournament aged 37. He struck the play-off effort that booked North Macedonia's EURO place at Georgia's expense and followed up with their first ever goal at the finals.
120 caps: Robert Lewandowski (Poland)
The archetypal centre-forward, Lewandowski has more appearances and more goals – 66 – for his country than any other player in history. His opening strike of EURO 2012 in Warsaw lives in the memory.
116 caps: Pepe (Portugal)
A combative defender who rarely takes a backward step, Pepe was at the heart of the Portugal rearguard that provided the platform for EURO 2016 success. He turned 38 in February.
110 caps: Axel Witsel (Belgium)
Perhaps a less revered member of the Red Devils' recent crop, midfield man Witsel has nonetheless been a regular fixture for Belgium for more than a decade.
109 caps: Toby Alderweireld (Belgium)
A long-time Tottenham and Belgium defensive stalwart, the versatile Alderweireld remains a classy performer at the back for club and country.
109 caps: Christian Eriksen (Denmark)
Danish Player of the Year five times out of the last nine, Eriksen burst onto the scene at a tender age and has embellished his reputation ever since, thanks to his creativity, set-piece delivery and eye for goal.
109 caps: Giorgio Chiellini (Italy)
A centre-back chiselled from the same rugged Italian mould as many who have gone before, Chiellini has been turning out for the Azzurri for 17 years and counting. Only six players have earned more Italy caps than the Juventus centre-back.
108 caps: Olivier Giroud (France)
Now five goals shy of France's all-time top marksman Thierry Henry, Giroud has often flown under the radar compared with some higher-profile team-mates but continues to enhance his reputation as both a great scorer of goals and scorer of great goals.
108 caps: Simon Kjær (Denmark)
A steadying presence at the heart of his country's defence, Kjær has had a varied club career, taking in spells in Germany, Italy, France, Turkey and Spain.
107 caps: Eden Hazard (Belgium)
Arguably the most venerated of Belgium's much-admired vintage, Hazard trails just Vertonghen, Witsel and Alderweireld among his country's most-capped players – and, with 32 goals, only Romelu Lukaku among their all-time top scorers. Recently beset by injuries, when fit he plays with a joie de vivre whatever the stage.
104 caps: Yuri Zhirkov (Russia)
Still going strong at 37, Zhirkov has been rampaging down Russia's left flank since 2005. Like many of his international peers, he shone brightest at EURO 2008 and figured in the Team of the Tournament.
104 caps: Leonardo Bonucci (Italy)
The cultured foil to Giorgio Chiellini's more muscular approach for Juventus and Italy during much of the past decade, Bonucci is a nine-time Serie A champion.
103 caps: Toni Kroos (Germany)
Germany and Real Madrid's metronomic midfielder, Kroos is a veteran of three World Cups and two EUROs – not to mention four UEFA Champions League triumphs.
103 caps: Thomas Müller (Germany)
Back in the Germany fold after more than two years out in the cold, Müller's stellar displays over the past couple of seasons have underpinned Bayern's success. He has managed more than a goal every three games at international level.
102 caps: Peter Pekarík (Slovakia)
First capped in 2006, Slovakia's right-back has spent the bulk of his domestic career in Germany and represented his country at the 2010 World Cup finals as well as EURO 2016.
102 caps: Ivan Perišić (Croatia)
A reliable forward option for Croatia since he made his debut in 2011, Perišić's proudest national-team achievement was equalising in the 2018 World Cup semi-final against England, his side making it to the decider with an extra-time winner.
101 caps: Chris Gunter (Wales)
An attacking full-back who was just 17 when awarded his first Wales cap in 2007, this year Gunter became the first Welshman to reach 100. A model of consistency.
101 caps: Manuel Neuer (Germany)
The Bayern No1, famed for his stand-out saves and outstanding ability to play as a sweeper-keeper, is one of the most decorated custodians of all time having won two UEFA Champions Leagues and countless honours at club level along with the World Cup in 2014.
All cap numbers are consistent with national association data. Only internationals included in EURO 2020 squads have been included.
