Barcelona ace Lionel Messi insists his foot injury is not serious.

Messi failed to play in Argentina's two friendlies last week.

"Back in Barcelona. The Tour in US was sweet and sour for me.

"We got 2 wins with a great job from everyone, but I couldn't play because of my swollen foot. It still hurts a bit, but I hope to recover soon so I can help the National team and FC Barcelona," he posted on Facebook.
