Lionel Andrés "Leo" Messi is an Argentine professional footballer who plays as a forward for Spanish club Barcelona and the Argentina national team.
But that's not all there is to know about him.
He was born June 24, 1987, when Ronald Reagan was president and everyone was listening to Whitey Houston's huge hit I Wanna Dance with Somebody (Who Loves Me.)
That also means "Leo" is really a Cancer, making him loyal, tenacious, intuitive and independent.
Messi's not tall, standing at only 5'7". He can blame a childhood hormone deficiency for that.

Technically, he's a middle child (third of four siblings). Not sure how that plays out for that whole eldest child/high achiever stuff.

Some call Messi the best player in the world. He is the captain of the Argentina national side and has played in three World Cups (2006, 2010 and 2014) and three Copa Américas (2007, 2011 and 2015). In the summer of 2008 he also played at the Beijing Olympics, and came home with a gold medal. You be the judge.
