Messi's Golden Boot chase and Argentina's bid to retain the World Cup collide with England's dream of ending a 60-year wait for another final.
Barely 24 hours after Spain produced a tactical masterclass to end France's World Cup dream, another heavyweight showdown awaits on Wednesday night when Argentina and England battle for the remaining place in the 2026 FIFA World Cup final.
The winner will face Spain in Sunday's title decider after La Roja stunned tournament favourites France 2-0 in Tuesday's first semi-final.
Few fixtures in world football carry as much history, emotion and intrigue as Argentina against England.
From unforgettable World Cup clashes to moments of controversy that have transcended generations, the rivalry has consistently produced matches that occupy a special place in football folklore.
Wednesday's encounter promises to add another chapter.
Argentina captain Lionel Messi will once again take centre stage as he pursues both national glory and the Golden Boot.
The eight-time Ballon d'Or winner heads into the semi-final with eight goals and two assists.
Following Kylian Mbappé's exit with France on Tuesday, Messi now has the clearest path to finishing as the tournament's top scorer after edging ahead on FIFA's tiebreak criteria.
Standing in Argentina's way is an England side equally determined to end decades of World Cup frustration.
Manager Thomas Tuchel is chasing his first major international trophy since taking charge of the Three Lions.
Harry Kane and Jude Bellingham will once again lead England's attack.
Both players have scored six goals and remain in the Golden Boot race, although they will likely need a prolific display to overtake Messi.
Argentina have looked every inch defending champions throughout the tournament. They topped Group J before defeating Egypt in the Round of 16 and overcoming Switzerland 3-1 in the quarter-finals to keep alive their bid to retain the trophy.
Victory over England would move Lionel Scaloni's men within one win of becoming the first nation to successfully defend the FIFA World Cup since Brazil achieved the milestone in 1962.
England have been equally impressive. The Three Lions finished top of Group L with two wins and a draw before edging Mexico 3-2 in a thrilling Round of 16 encounter despite playing much of the contest with 10 men after Jarell Quansah was sent off.
They then eliminated Norway in the quarter-finals to move within one match of reaching their first World Cup final since 1966.
Adding another layer of intrigue, this will be Messi's first competitive match against England's senior men's national team.
Given the historic rivalry between the two footballing nations, local authorities in Atlanta, working alongside the FBI, have designated the fixture as the tournament's highest-security match, with enhanced security measures in and around the stadium.
With 101 of the tournament's 104 matches already completed, only three remain to determine the next world champions and third-place finishers.
When the final whistle blows in Atlanta, one football giant will move within touching distance of immortality, while another will see its World Cup dream end just one step short of the grandest stage.
