Lionel Messi put his Barcelona troubles behind him to fire Argentina to an opening 1-0 victory over Ecuador in World Cup qualifying. The 33-year-old great has been in open conflict with his club but it had no detrimental effect on his form as his 13th minute penalty was the difference in a tight encounter. The six-time Ballon d'Or winner unsuccessfully tried to force his way out of the Catalan giants in the close season but he seemed much happier in the light blue and white jersey of his country.
