Lionel Messi will line up for Argentina and Kylian Mbappé will be on the opposite side for France tomorrow in the World Cup final.

Messi has been there before, but lost in the 2014 final to Germany. Mbappé won the 2018 title after scoring a goal against Croatia.

However, neither will be able to win the gold trophy entirely on their own at Lusail Stadium.

Here is a look at some of the key players on both teams, and their coaches:

LIONEL MESSI

The 35-year-old Messi is the heart and soul of the Argentina team, the tournament’s co-leading scorer with five goals and tied for the most assists with three. Look for the Paris Saint-Germain forward to burst into creative life when he sees a chance to make something happen. A World Cup title would finally complete Messi's elevation alongside Diego Maradona to icon status.

JULIAN ALVAREZ

Alvarez made it off the bench to replace Lautaro Martinez as the World Cup progressed and scored four goals in four starts with Argentina. The 22-year-old Manchester City player is a powerful runner who created a perfect partnership with Messi in the 3-0 win over Croatia in the semifinals.

EMILIANO MARTINEZ

Martinez is an imposing 6-foot-4 goalkeeper with a personality to match his stature. “Dibu” would be favoured if the final goes to a penalty shootout. The 30-year-old Aston Villa keeper made key saves in Argentina's shootout win over the Netherlands in the quarterfinals and in last year's Copa America semifinals.

NAHUEL MOLINA

Molina is an energetic fullback with the toughness expected of any Argentina defender. The 24-year-old Atletico Madrid defender also has attacking instincts. He received the no-look pass of the tournament from Messi to score against the Netherlands.

ENZO FERNANDEZ

Fernandez started the tournament as a substitute but was in the team to stay after scoring with his fast feet and a curling shot in Argentina's victory over Mexico. The 21-year-old Benfica player anchors the center of midfield and will be trying to stop Antoine Griezmann’s forward forays.

LIONEL SCALONI

Scaloni was an assistant coach at the 2018 World Cup — when Argentina exited in the round of 16 against France – and is now an unheralded success in the top job. He brought a 35-game unbeaten run to Qatar that included ending a long wait for a Copa America last year. The 44-year-old Scaloni has succeeded in surrounding Messi with a midfield that lets him flourish.

KYLIAN MBAPPE

Mbappé is France's fastest, most dynamic scoring threat on the field. The 23-year-old Paris Saint-Germain forward is tied with Messi with a World Cup-leading five goals. A standout game against Argentina will place him among the all-time greats.

ANTOINE GRIEZMANN

The 31-year-old Griezmann has been a revelation for France at this year's World Cup. Once a goal-scoring winger, the Atletico Madrid forward has added relentless defensive protection to his creative craft. A duel could develop with Messi between the lines of Argentina’s attack.

HUGO LLORIS

The 35-year-old Tottenham goalkeeper is poised to become the first-ever captain of two World Cup-winning teams. A quiet-spoken leader by example, he now holds France's all-time appearance record.

RAPHAEL VARANE

At his third World Cup, the 29-year-old Varane is a fixture in the centre of a French defence that keeps changing because of injury and illness. The four-time Champions League winner at Real Madrid is back to near his elegant best after an injury scare in October.

AURELIEN TCHOUAMENI

Tchouaméni arrived on the world stage ahead of schedule in the midfield role Paul Pogba had for France four years ago. He matched Pogba’s shooting power with his goal against England. Learning at Real Madrid this season, after spurning Mbappé’s urging to go to PSG, should prepare the 22-year-old midfielder for facing Argentina.

DIDIER DESCHAMPS

In his 11th year as France coach, Deschamps can become only the second man to lead two World Cup-winning teams and the first since 1938. The 54-year-old Deschamps has integrated inexperienced players to replace injured veterans without losing any of his team’s typical calm assurance.
