Kasimpasa pulled off the surprise of the week after beating Galatasaray 2-1 in the Istanbul derby on Sunday.
The Istanbul minnows came from behind to topple the Lions who would have gone top with a victory.
Chelsea loan centre-back Kenneth Omeruo started for the home side and put on another stellar defensive display.
The Nigeria international made three tackles for the Istanbul minnows and the highest number of clearances in the entire game (14).
Omeruo made his feelings about the victory very clear after the game on Instagram.
The 24-year-old shared a photograph from the game: “What a game.. great victory for us.. #kasimpasa 2-1 #galatasaray good team spirit..”
