1.Lionel Messi & Nicolás Otamendi – The Oldest, both 38 years old2. Argentina has 2 players tied as the oldest in Scaloni’s squad. Both were key to Qatar 2022 and are back for one final run.

Lionel Messi, 38 Position: Forward / Right WingerClub: Inter MiamiJersey: #10 | Caps: 198 This is Messi’s 6th World Cup, breaking Lothar Matthäus’ record for most tournaments played. He turns 39 on June 24, 2026, right in the middle of the group stage.

2026 Role: Scaloni says Messi will be “even more monumental” this time. Less pressing, more playmaking. He’s evolved into a deep-lying creator who picks passes and dictates tempo. Still Argentina’s penalty taker, free-kick specialist, and emotional leader.

World Cup legacy: 13 goals + 8 assists across 5 World Cups. Won the Golden Ball in 2014 and 2022. The whole squad is built around giving him one last shot at defending the title. Quote: Otamendi calls him a “competitive animal” who “doesn’t let you relax in training”.

Nicolás Otamendi, 38 Position: Centre-back Club: BenficaJersey: #19 | Caps: 130 The heart of Argentina’s defence. 130 caps of experience and zero fear. Otamendi was the vocal leader in Qatar and remains Scaloni’s most trusted defender.2026 Role: Organize the back 4, mentor young CBs like Lisandro Martínez & Cristian Romero, and bring winning mentality. At 38 he can’t play 90 mins every 3 days, but he’s the “locker room general”.Style: Aggressive, last-ditch tackles, brilliant in the air. Known for playing through pain. Benfica fans call him “El General.Together: Messi + Otamendi = 328 caps of World Cup, Copa América, and Champions League experience. They’re the bridge between 2014 heartbreak and 2022 glory.

3. Valentín Barco & Nico Paz – The Youngest, both 21 years old Scaloni kept 17 players from Qatar 2022, so youth is limited. But 3 players are under 25, with Barco & Paz tied at 21.Valentín Barco, 21 Position: Left-back / Midfielder Club: StrasbourgJersey: #8 | Caps: 2Scaloni calls him a “fresh addition for the future”. Barco is a modern left-back: quick, technical, comfortable inverting into midfield. Only 2 caps but already trusted in a 26-man World Cup squad. Why he’s there: Argentina lacked a true left-back after Acuña’s injuries. Barco gives width, energy, and 1v1 dribbling. Can also play left midfield in a 4-4-2.2026 Role: Backup to Tagliafico + impact sub. At 21 he’s learning from Otamendi daily. Scaloni sees him as Argentina’s left-back for 2030.

Fact: One of only 3 players under 25 in the entire squad. Nico Paz, 21 Position: Attacking MidfielderClub: Como, ItalyJersey: #18 | Caps: 8 The most hyped youngster in Argentina. Market value ~€80m after Real Madrid → Como move. Played with Bellingham + Modrić at Madrid before choosing Como for minutes. Why he’s special: Left-footed #10 with vision, late runs into the box, and set-piece quality. Scaloni + fans are “keen and eager” to see him because he’s the clearest post-Messi creative option.

2026 Role: Messi’s understudy. Will come off the bench when Argentina needs a unlock vs low blocks. Already has 8 caps at 21, showing Scaloni’s trust. Fact: Scored for Argentina vs Brazil in 2024 qualifiers. If Messi rests, Paz takes the #10 shirt.3rd youngest: Giuliano Simeone, 23 – Diego Simeone’s son, high-energy winger. The 17-year gap: Messi/Otamendi at 38 vs Barco/Paz at 21 = 17 years. That gap tells Scaloni’s story: Win now with the legends, but Barco + Paz are already being groomed to lead Argentina in 2030.
