Portugal v Argentina usually would have meant Cristiano Ronaldo v Lionel Messi, in what would have been one of the biggest matches in world football. However, this Portugal v Argentina match will not have the two superstars lining up, as the two teams get their U-23 men's football campaigns at the Rio Olympics 2016 underway on Thursday.
Argentina endured more pain in a major final at the end of June, when Chile beat them on penalties in the Copa America Centenario. That led to Messi announcing his retirement from international football and the coach Gerardo Martino stepping down, with new manager Edgardo Bauza being appointed.
Julio Olarticoechea will be the manager for the U-23 team, and owing to club resistance and a general lack of interest, this Argentina side are not as power-packed as it could have been.
Atletico Madrid's Angel Correa will lead the attacking line for Argentina, along with Jonathan Calleri, while Geronimo Rulli, who has been heavily linked with a move to Manchester City, will want to make an impression ahead of the potential transfer to the English Premier League and Pep Guardiola's side.
The Portugal side also have a few familiar faces, including Joel Pereira of Manchester United and Liverpool centre-back Tiago Illori. Neither team have the obvious big names of a Brazil, who have named Neymar, Gabriel Jesus and Gabriel Barbosa in their squads, but knowing the talent that comes from these two sides and the fact that the other two countries in Group D are Algeria and Honduras, both Portugal and Argentina will, at least, be expected to reach the next round of the men's competition of the Rio Olympics.
