An Afghan boy who became an online hit after wearing a homemade shirt bearing Lionel Messi's famous number 10 has met his hero. The Barcelona superstar sent a signed Argentina shirt to the child earlier this year, but has now gone a step further and met his biggest fan. While in Doha for a friendly match between Barcelona and Al Ahli, Messi posed for a picture with the youngster. Later on Tuesday, Messi walked out onto the pitch holding hands with Murtaza.
