Lionel Messi says that his Argentina side have to improve despite seeing off Bosnia and Herzegovina 2-1 at the Maracana on Sunday.
Messi scored what proved to be the winning goal with a trademark run and sublime shot; something we have grown to expect from the Argentina captain.
Despite this, Argentina were very poor in the first half and only lead through an unfortunate own goal as Bosnia and Herzegovina enjoyed the majority of possession.
Messi himself was not up to scratch as he looked nervous after so much hype and expectation surrounded the 26-year-old before a ball was kicked.
Be that as it may, the most important thing for any team at the World Cup is to pick up three points in their opening game and Argentina did that, much to their relief.
Even though they have been handed the easiest group, improvement is needed if they are to progress and the Barcelona man knows this.
"It's important that we started off on the right foot with the three points, but we do have things we must improve," Messi told reporters.
"It's not easy with all the anxiety and the nerves, but the important thing is the result. We had a great second half. We had the ball much more, created several opportunities and that's what we have to continue to do."
Argentina coach Alejandro Sabella even explained how poor his team were and that his changes at half time to support his captain were crucial to winning the game.
This again, highlights how much focus and pressure is on Messi and how if he doesn't perform, neither do his teammates.
