Spor Toto Super League's fourth week ended with disappointment for Turkish football "Big Three" - Galatasaray, Fenerbahçe and Beşiktaş. All the Istanbul powerhouses lost points in the fourth week matches while Istanbul minnows Kasımpaşa have taken the lead in the standings making four in four. New leader Kasımpaşa won against MKE Ankaragücü 1-0 on Sunday in its home stadium and with this result it has won four consecutively in the first four weeks in the Super League. Galatasaray who were on top spot ahead of the fourth week, got thrashed by Trabzonspor 4-0 in Trabzon on Saturday. The other powerhouse Fenerbahçe is already in a worst situation among Istanbul's Big Three after losing three matches back to back, earning just three points in four weeks.

As for Beşiktaş, the Black Eagles entered the fourth week with big hopes after its rivals Fenerbahçe and Galatasaray got beaten. Ahead of the fourth week Beşiktaş were on six points and wanted to catch Galatasaray with nine points.
