Argentina coach Lionel Scaloni said he did not want to "raise the alarm" shortly before their World Cup opener, but admitted "many players are not yet 100 percent fit" for the defending champions.

Superstar Lionel Messi watched Saturday's 2-0 friendly win over Honduras in College Station, Texas from the bench.

The captain of the Albiceleste, who will soon be 39, had recently been struggling with a thigh muscle issue.

"Leo is making good progress, he has already trained partly with the team and that is very good," Scaloni had said before the match against Honduras.
