Born in Sofia, Anton Vergilov was educated to football in Levski's youth academies.
In 2002, the 17-year-old Vergilov signed his first professional contract with the club from the Suhata Reka neighborhood.
However, due to the great amount of competition in the defensive roles, he was loaned for four years to Rodopa Smolyan.
With the team from Smolyan, Vergilov achieved 62 appearances in the top divisions of Bulgarian football and his good displays as a defender were used again in the following years, while playing for Beroe Stara Zagora and Marek Dupnitsa.
