It was courtesy of his brother, who had posted his pictures wearing the blue and white plastic bags on Facebook.
The six-year-old boy became a rage, and that led to a campaign that was launched on Twitter to track down the boy who was pictured wearing blue and white plastic bag with 'Messi 10' written on the back of it.
It took around 10 days to find out who the young boy was, who had attracted a million of people's attention for exhibiting his immense love for Messi.
Afghanistan's Murtaza Ahmadi has reminded us that there does not come a price tag with the wish to dream. The tiny eyes, who had never been outside the Taliban controlled region, had dared to dream big.

The FC Barcelona star not only sent him a signed jersey earlier, he gave Murtaza memory for a lifetime when he met the kid in Qatar on Tuesday.

Messi and Co were in Qatar for a friendly match against Saudi Arabian Al Ahli.
Murtaza, who was given the honour to bring the match ball out onto the pitch before the match, ignored the referee's attempts to take him for the pitch before running over to Messi on the edge of the semi-circle.

As Luis Suarez and Messi broke down into laughter, Murtaza's lifetime experience ended when the referee, who was laughing as well, picked up the six-year-old and walked off the field.
"We do not have a football playground near our house, and the only ball I have is punctured. “I want to be like Messi when I grow up," Murtaza said.
Although the fairytale meeting lasted for a short span of time, it was the world for Murtaza!
