Talisman Lionel Messi barely got a sniff, as his hunt for a goal at the 2018 World Cup went on.
Willy Caballero – 4
Made a decent save to deny Ivan Perisic in the first half but never looked comfortable with the ball at his feet. Terrible error gifted Croatia the opener when he tried to chip the ball over Rebic.
Gabriel Mercado - 4.5
Looked uncomfortable throughout on the right side of of a back three.
Nicolas Otamendi - 4
Regularly misplaced passes and looked a shadow of the player who impressed for Manchester City last season.
Nicolas Tagliafico - 5
Started a couple of attacks from the back but was also exposed by Argentina's system.
Eduardo Salvio - 5
Threatening at times going forward but showed little defensive awareness in the right wing-back role. Subbed off early in the second half.
