Cristiano Ronaldo, Robert Lewandowski and the veterans likely playing their final tournaments at Euro 2024

This feels like the end of the road for the 35-year-old striker, who wasn't particularly impressive for Inter during the 2023-24 campaign. However, Arnautovic may hang around for a little while yet, given he's only eight goals shy of Toni Polster's Austria record (44).

De Bruyne certainly still has the talent to continue playing until the 2026 World Cup, but the attacking midfielder, who turns 33 later this month, has a history of fitness problems, meaning he could easily decide to retire from international football in the hope of prolonging his club career.

After all, if Belgium win, there's probably little point in hanging around; lose and De Bruyne would probably decide he's had enough disappointment with the Red Devils.

The 37-year-old striker has already revealed that not only will he move to MLS with LAFC this summer, he'll also call time on his international career after the Euros. "We need to make way for the youngsters," the World Cup winner told L'Equipe. "You also have to be careful not to have one year too many."

Griezmann is a player who's long relied on his remarkable footballing intelligence to thrive at the highest level, so he could, in theory, carry on until 2026. But the multi-talented 33-year-old has already won and done it all for France. It wouldn't be a surprise to see him walk away this summer.

Even at 33 years of age, Germany's captain is still a formidable force at the highest level and he'll be dreaming of lifting the Henri Delaunay trophy on home soil this summer. If he does, Gundogan would likelly view it as the perfect time to bow out, so that he could focus solely on putting Barcelona back on their perch.

Truth be told, it was a shock to see Kante recalled for the Euros, given his constant injury issues over the past few years and the fact that he's now plying his trade in Saudi Arabia. So, while Didier Deschamps says the midfielder has "regained all of his physical capabilities", the Euros is almost certainly the 33-year-old's international swansong.

We already know that Kroos isn't just retiring from international duty after the Euros, he's hanging up his boots for good. Before playing a predictably pivotal role in Real Madrid winning a 15th European Cup, the German midfielder announced he'll retire from football after the Euros. "My ambition was always to finish my career at the peak of my performance level," the 34-year-old said.

The 35-year-old striker scored 26 times in all competitions last season, but there was plenty of evidence to suggest that Lewandowski is starting to slow down. He might not have the energy or desire to go through another World Cup qualification campaign, particularly if Poland disappoint again at a major tournament.

The iconic midfielder has already decided to play on for another year at Real Madrid, but it would be a major shock if he decided to keep playing for Croatia after the Euros, much as Modric loves his country. The neutrals will be hoping that the 38-year-old bows out with the winners' medal his talent so richly deserves after so many near-misses with one of football's biggest overachievers.

It's crazy to think that the versatile right-back is preparing for a major international tournament at the age of 38, given he used to suffer from chronic homesickness - and to such an extent that he would pull out of training camps in Spain if they were located too far from his native Seville. It's a credit to both his talent and mental toughness that he's still going. Nonetheless, Navas is almost certain to say goodbye to La Roja after the Euros.

Neuer turned 38 in March but remains Germany's No.1 going into the Euros. He'll, thus, be hoping to win a European Championship 10 years after lifting the World Cup. Whether he does or not, though, Neuer is expected to finally step aside and let Marc-Andre ter Stegen have a go at establishing himself as the starter.

Love him or loathe him, you've got to respect the fact that Pepe is still going strong at 41 years of age. The man is so driven, and so determined, that you obviously can't rule out him continuing until the 2026 World Cup in North America, but the feeling is that the Euro 2016 winner will call it a day after this summer's tournament, particularly as Portugal are no longer lacking in quality young centre-backs.

We thought we'd seen the last of Ronaldo on the international stage as he tearfully made his way down the tunnel after Portugal's shock World Cup loss to Morocco - a game that the forward began on the bench. However, he's spent his entire career surpassing expectations - and breaking records - and is now set to make more history in Germany.

Ronaldo is now 39, so international retirement appears to beckon, but his body is clearly benefiting from the low standard of play in Saudi Arabia, meaning nothing can be ruled out - which has always been the case when it comes to one of the most impressive physical specimens the game has ever seen.

The centre-half made his 150th appearance for his country in a qualifier against Estonia last September and marked the occasion by opening the scoring in a 5-0 win, underlining his continued importance to his country, both as a defender and as a leader. However, given he's just turned 37, the likelihood is that the Euros will be Vertonghen's last tournament at international level.

The versatile Manchester City right-back is something of a freak of nature in that he's 34 and yet remains capable of outpacing wingers 10 years his junior. The Three Lions will be hoping that Walker plays on no matter what happens in Germany (particularly as Ben White has shown little interest in ending his international exile), but he'd be forgiven for feeling he'd be better off concentrating on enjoying his final few years in club football.
