According to the Mirror's Ed Malyon, three-year-olds Thiago Messi and Milan Pique, along with Benjamin Suarez—who celebrates his third birthday on September 26—enjoyed their first day at Barca's "FCB Escola," which is open to the children of all club employees.
The school, which has football classes for the children on Mondays and Wednesdays, can serve as a gateway into the club's La Masia academy—where the older Messi and Pique learned the tricks of the trade—and is intended to instil the "Barca DNA" in their play from a young age.
