He left the Super League and transferred to the 2nd League

Ertuğrul Ersoy, who parted ways with Gaziantep FK, returned to Bursaspor, where he started his football career. The green-whites, who were promoted to the 2nd League by becoming champions in the 3rd League 1st Group, rolled up their sleeves to establish an ambitious squad for the new season, and one of their first moves was to add the 28-year-old defender, who was trained in the youth academy, back to the squad.
The transfer, which was announced on Bursaspor's social media account with the message "Welcome home Ertuğrul", also created great excitement among the fans. Ersoy, who came up through the club's infrastructure, previously wore the jerseys of Rizespor, Le Havre, İstanbulspor and most recently Gaziantep FK. The experienced player, who played in 22 matches and scored 1 goal for Gaziantep this season, mutually terminated his contract with the club in recent days.
Bursaspor, which has determined its goal as rising again in the new season, has both strengthened its defensive line and added a name with high sense of belonging to the club to its squad with this transfer.
