Turkish Spor Toto Super Lig's two undefeated teams will square off in Istanbul as front-runners Medipol Basaksehir travel to city rivals Besiktas at 7 p.m.
The league's 12th week kicked off with two matches Friday, Galatasaray beating Bursaspor 3-1 to avoid a three-game losing streak.
Already hurt by Medipol Basaksehir and Fenerbahce losses in the past two weeks, the Lions started the match poorly and conceded a goal in only the 14th minute.
