Even in the world of soccer where many midfielders are undersized, at 5'7" Messi stands out for being especially small. This is due in part to his being diagnosed with Growth Hormone Deficiency (GHD) at age 11, a condition that (obviously) stunts a child's growth. Sounds to us like a good excuse to take a whole bunch of HGH.
He is small partly because of a growth hormone deficiency discovered when he was 11.
