Argentina and Egypt will collide in the World Cup last 16 on Tuesday in a match that offers far more than a meeting between the reigning champions and Africa's most successful national team.
It will also bring together team captains Lionel Messi and Mohamed Salah for what is likely to be the only and final World Cup clash between two of football's defining figures of the modern era.
For Argentina, the match is another step in their bid to retain the trophy they lifted in Qatar four years ago.
For Egypt , it is an opportunity to produce one of the greatest results in the country's footballing history by eliminating the holders and reaching the quarter-finals for the first time.
Now 39, Messi is widely expected to be playing the last World Cup of a glittering career that has already delivered every major honour in the game, including the one prize that had long eluded him before Argentina's triumph in 2022. Salah , 34, has similarly cemented his place among football's elite through his exploits in Europe, but a deep run at a major tournament has never defined his international career. Leading Egypt beyond the defending champions would rank among the greatest achievements of his time in the national team's colours.
While both players have dominated world football for more than a decade, opportunities to face one another have been rare, making Tuesday's meeting a fitting chapter in two remarkable careers.
Both have also come to represent far more than their national teams.
Messi remains the sporting icon of Argentina and one of Latin America's greatest footballing heroes, while Salah has become arguably Africa and the Middle East's most recognisable and admired athlete.
Argentina arrive in Atlanta as favourites, but not without questions after being pushed to the limit by World Cup debutants Cape Verde in the previous round.
Lionel Scaloni's side required extra time to edge a thrilling 3-2 contest after surrendering two leads, exposing defensive vulnerabilities that had been largely absent during the group stage. Messi himself admitted afterwards that Argentina had plenty to improve before facing Egypt. Egypt also endured a draining last-32 encounter, defeating Australia on penalties after a 1-1 draw that stretched to 120 minutes.
Salah, who has been carrying a hamstring injury, completed the match and converted an audacious Panenka in the shootout before describing the victory as a historic moment for Egyptian football.
The physical demands of those victories mean both teams enter the tie with only a short recovery period, although Argentina have publicly acknowledged the challenge posed by an organised Egyptian side built around defensive discipline and rapid counter-attacks led by Salah and Manchester City's Omar Marmoush. Egypt have already made history by winning their first-ever World Cup knockout match, but an even greater prize now awaits. Victory over the reigning champions would represent one of the biggest shocks of the tournament and the finest result in the Pharaohs' World Cup history.
The Argentinian objective is equally clear: keep alive their title defence and Messi's pursuit of ending his extraordinary World Cup career with one final deep run.
Meanwhile, for non-football fanatics, the occasion offers a rare chance to see two of football's greatest players, each carrying the hopes of millions, sharing the World Cup stage for what is almost certain to be the last time.
