Messi, 35, will be looking to establish his place in the pantheon of the game's all-time greats at this year's tournament as he bid to life the prestigious trophy for the very first time in his career.
The seven-time Ballon d'Or winner managed to get his hands on his first major international trophy when he guided Argentina to Copa America glory in 2021, and he is now hoping for more success at his fifth - and potentially last - World Cup.
Messi scored five of his 90 international goals for Argentina in World Cup Qualifying, and the legendary forward will be a key asset for Lionel Scaloni's side.
Argentina's No.10 is one of six attackers who have been selected in Scaloni's squad, along with Roma's summer signing Dybala, who has made the cut despite his recent injury concerns.
The 28-year-old has been sidelined since early October and has subsequently missed eight matches in all competitions due to a hamstring injury.
However, the 34-cap forward will be heading to Qatar and he has is in contention to feature for Jose Mourinho's Roma side against Torino on Sunday after stepping up his recovery in training.
Inter Milan's Lautaro Martinez and Joaquin Correa, Manchester City's Julian Alvarez and Sevilla's Papu Gomez will also be competing for a place in attack for Scaloni's side.
Argentina's squad consists of five Premier League players, with Alvarez joined by Manchester United's Lisandro Martinez, Aston Villa's Emiliano Martinez, Tottenham Hotspur's Cristian Romero and Brighton & Hove Albion's Alexis Mac Allister.
