 In the summer of 2014 Filipov remained in Botev Plovdiv despite the financial crisis in the team.Velislav Vutsov preferred to use Bozhidar Vasev and Yordan Hristov as left and right defender therefore Filipov remained on the bench in most games.After the replacement of Vutsov as a manager, Petar Penchev started to use Bozhidar Vasev as a midfielder and Filipov or Lazar Marin were more often included in the starting lineup on the left side of the defense.
