Career
In the summer of 1997, he was signed by Levski Sofia on the insistence of coach Stefan Grozdanov and manager & player"s agent Andrey Zhelyazkov. He is the second Levski Sofia player (after legend Nikola Kotkov) to score a hat-trick for the team in European competitions. However, shortly after that he returned to Loko Sofia and his career began to stagnate, with the football player never reaching his previous heights.
Borisov subsequently had a stint in Israel (first moving to the country in 2000) with Bnei Sakhnin and Hapoel Ramat Gan.
He then played for Loko Sofia, Dorostol Silistra, Balkan Botevgrad and Minyor Pernik before retiring. After the end of his playing career, Borisov studied to become a manager in Dimitar Penev"s coaching school between 2007 and 2008 and also took a number of other jobs outside of sports.
His current focus is his own private footballing school "Ferion", where he works with the children. Borisov is regarded as a very talented football player who fell short of fulfilling his full potential.
