After a convincing 3-0 win in the quarter-finals, Argentina may opt to deploy an unchanged side for Wednesday's Copa America semi-final clash with Colombia.

Talismanic forward Lionel Messi will continue to lead the attack, having hit four goals and four assists in five Copa America appearances, despite ongoing attention around the expiration of his Barcelona contract at the beginning of July.

Lautaro Martinez should also keep hold of his place after an impressive performance last time out, including scoring Argentina's second goal to put the game out of sight with five minutes to go.

There is plenty of competition for places in attack, though, as Martinez will battle with the likes of Angel Correa, Angel Di Maria and Nicolas Gonzalez for a spot.

New Barcelona forward Sergio Aguero will also hope for a starting place, having moved to Spain in the summer after leaving Manchester City.

Further back, the midfield trio of Rodrigo De Paul, Leandro Paredes and Giovani Lo Celso continued to impress last time out, and Lionel Scaloni should again deploy all three players for the semi-final.

They will shield a back four that has looked more secure as the tournament has progressed, with the pairing of Nicolas Otamendi and German Pezzella looking solid at the heart of the defensive line in their win over Ecuador.

Emiliano Martinez will continue to line up between the sticks, having continued his form into the Copa America after being one of the Premier League's standout goalkeepers last season in his first campaign since moving from Arsenal to Aston Villa.

Argentina possible starting lineup: E Martinez; Molina, Pezzella, Otamendi, Acuna; Paredes, De Paul, Lo Celso; Messi, Aguero, L Martinez
