Basaksehir secured their third consecutive win with a 2-1 victory over Hatayspor at the Mersin Stadium last Saturday.
Cagdas Atan's men took the lead through Krzysztof Piatek in the fifth minute before Olivier Kemen doubled the advantage in the 69th minute. The Grey Owls held on for the win despite Hatayspor pulling a goal back in the 73rd minute.
As a result, Basaksehir have climbed to fourth place in the Turkish Süper Lig table, one point ahead of Besiktas in the race for European qualification.
Next up is an opposing team they have beaten in the last seven meetings, with six of those coming in the Super Lig.
Currently on a four-match unbeaten run on home soil, the hosts will hope to extend this streak on Sunday against a side they have defeated 10 times in 18 home games.
Kasimpasa ended a two-match losing streak with a 1-0 victory over Samsunspor at the Recep Tayyip Erdoğan Stadium last Saturday, courtesy of Aytac Kara's early goal.
The Apaches remain seventh in the Turkish Super Lig table, three points behind Sunday's opponents in the race for the final European spot.
After ending a run of two consecutive away defeats with a win over Gaziantep in their last away match, the visitors will be hoping to win two away games in a row for the first time since January.
They are the fourth-best team on the road this season, having picked up 24 points from 17 away matches. However, their last victory against Sunday's opposition came back in 2020.
