Messi said farewell to the Argentina national team on Tuesday, scoring one goal and setting up two others in a 3-0 friendly win over Benin. The 39-year-old left as his country's most-capped player, with 208 appearances, and its record scorer, having capped years of international frustration with World Cup and Copa America triumphs.
His immediate task is to lift Inter Miami out of a five-match winless run in Major League Soccer. Miami (12-5-10, 46 points) sit third in the Eastern Conference, level on points with New England, who hold the tiebreaker with 14 wins.
Miami have won only once in their last 10 league matches. They took the Campeones Cup on September 16 in the first game under newly hired coach Kily Gonzalez, but have since drawn with San Diego and lost 2-1 at Columbus.
"Leo is a person who every day conveys it and passes it on to his teammates, and he demands from all of us that you have to be at 100% in every way," Gonzalez said on Friday.
Messi has been in strong form this season with 21 goals and 13 assists in league play as he chases a third consecutive MLS MVP award, but Miami will need more contributors if they are to arrest the slide.
DC United (6-8-12, 30 points) arrive in 11th place, three points behind the final playoff spot in the conference and desperate for a result after a three-match winless streak. Their last victory came on September 9. The two sides met in Baltimore on March 7, when Messi and Rodrigo De Paul scored in a 2-1 Miami win.
