Representing your country in a World Cup is often seen as a major honour in a footballer's career, and very few players ever get the experience of lifting the World Cup trophy.
The 2018 World Cup, which begins next week, will showcase some of the finest talent ever seen in the tournament, but for some of the players, it may well be their last shot at World Cup glory.
While winning the World Cup is the greatest moment of a footballer's career, the tournament can also be a cruel stage on which to bow out. Just ask Zinedine Zidane.
A lot of the players on this list are not likely to be hanging up their international boots straight after the World Cup in Russia but given their age, it seems highly likely that it will be the last time they will get a chance at winning the World Cup as a player.
Of course, some footballers continue to defy age and may make one final appearance in Qatar but given their current circumstances, these are 10 players who will probably be making their final World Cup appearance in Russia.
10. Jamie Vardy (England)
Jamie Vardy's fairytale rise to the top of English football has been one of football's best stories in recent years and the former Fleetwood striker's story will be complete when he plays for England in the World Cup this Summer.
Sadly, for Vardy, Russia is likely to be his only World Cup appearance for the Three Lions, with the Leicester City striker making his World Cup debut at the age of 31.
9. Mario Gomez (Germany)
After initial speculation that he may not be included in Joachin Low's squad for the World Cup, Mario Gomez was confirmed as a member of the German squad this past week.
Germany's all-time top goal-scorer in the European Championships may not be in Low's starting 11 in Russia but he will be happy that he made the squad after not being a part of the 2014 World Cup winning squad.
8. Thiago Silva (Brazil)
Thiago Silva captained Brazil in 2014The 33-year-old defender tasked with captaining Brazil in the 2014 World Cup, Thiago Silva will be out to end his World Cup career with a bang in Russia.
After being an unused substitute in 2010 and then leading the team in an ultimately humiliating campaign in 2014, Thiago Silva will be hoping to end his last World Cup holding the trophy this year, and a quick look at Brazil's squad tells you that that is a very realistic possibility.
7. Tim Cahill (Australia)
Australian Socceroos Training SessionTalk about a veteran. Tim Cahill, the 38-year-old ex-Everton star was announced as part of the Australian squad this past week and frankly, it's not really that much of a surprise.
Cahill has been the star of the Australian squad for years, and while it is unlikely that the Socceroos will come away with anything other than a token victory, Cahill will be hoping he can help mount a challenge for the round of 16 against group rivals Denmark and Peru.
6. Gerard Pique (Spain)
Pique is inarguably one of the best center-backs in the game. If some Spanish fans had their way, Gerard Pique wouldn't be playing for Spain in the World Cup this summer.
Despite winning La Liga in comfortable fashion, and proving himself as one of the best center-backs in the world, Pique has become an unpopular figure in Spain due to his support for the Catalonian Independence movement.
5. Vincent Kompany (Belgium)
When he's not injured, Vincent Kompany has been one of the key components to Manchester City's success in recent years, and he will be hoping to replicate that as he fights for fitness for Russia.
Kompany was named in Martinez's squad for the tournament, despite picking up an injury in a friendly against Portugal last week.Martinez sighted Kompany's leadership qualities as a key reason he wants him in Russia, and Belgium fans will be hoping to see him make a brief appearance, at the very least.
4. Sergio Ramos
Real Madrid Celebrate After Victory In The Champions League Final Against LiverpoolIt would have been easy to place a lot of the players on the Spanish squad on this list.
We have already had Gerard Pique make an appearance, and the tournament is also going to be the last time we see either David Silva or Iniesta represent their country on the grandest stage in football.
3. Luis Suarez (Uruguay)
Luis Suarez had a pretty decent seasonWhat would a World Cup be without a spot of controversy from Luis Suarez? A moment of madness from the Uruguayan has become a staple of the modern game, and Russia will likely be his last chance to grab the headlines in a World Cup.
2. Cristiano Ronaldo (Portugal)
Despite being 33 years old, Cristiano Ronaldo is still one of the two best footballers on the planet, and his presence will be missed whenever he does inevitably hang up his boots.
Real Madrid suffered a poor season in La Liga due to a bad start, but Ronaldo has still continued to shine for Los Blancos throughout the campaign, especially in the Champions League.
1. Lionel Messi(Argentina)
Lionel Messi, like Cristiano Ronaldo, is often considered as the greatest player of his generation. Despite his unrivaled success at club level, Messi has never managed to bag any major silverware for Argentina, coming up short in the 2014 World Cup final and losing in three Copa America finals.
