Match Telegraph reported that representatives from Lech Poznań attended the derby between Levski and CSKA Sofia on Saturday to observe the 22-year-old Bulgarian international Marin Petkov and his teammate Svetoslav Vutsov. Petkov is an attacking midfielder, and according to foreign media, he nearly joined another Polish club, Raków Częstochowa, during the summer transfer window.

Petkov, who has 20 caps and 3 goals for Bulgaria, joined Levski in July 2019. He has 6 goals and 2 assists in 13 league appearances this season, and his market value is estimated by Transfermarkt to be €3.50m.
