With the transfer window reaching a dramatic conclusion and European group stages fast approaching, Matchday 4 of the Trendyol Süper Lig delivers a packed slate of fixtures. The headline event sees Jose Mourinho’s Fenerbahçe host Beşiktaş in a massive Istanbul derby, while Galatasaray face a tricky test away to Başakşehir and Trabzonspor look to bounce back under intense pressure.
Here is your complete preview and predictions guide for Matchday 4.
İstanbul Başakşehir vs Galatasaray
Kickoff: Friday, September 4, 18:00 BST / 20:00 Local
Venue: Başakşehir Fatih Terim Stadium, Istanbul
Galatasaray enter Matchday 4 sitting top of the Süper Lig table after grinding out a 3–2 victory over Göztepe last weekend. Victor Osimhen opened his account for the season with a second-half penalty, and the Lions have further bolstered their squad with the marquee signing of Rafael Leão from AC Milan and loan arrival El Chadaille Bitshiabu.
Başakşehir remain difficult to break down at home under Çağdaş Atan, drawing 1–1 with Kasımpaşa last time out. Eldor Shomurodov continues to look sharp up front, but stopping Galatasaray’s revamped frontline—featuring Osimhen, Leão, and Gabriel Sara—will be a monumental task.

Venue: Chobani Stadyumu FB Şükrü Saracoğlu, Istanbul
The marquee fixture of Matchday 4 sees two undefeated title contenders collide in the Asian side of Istanbul. Fenerbahçe enter the derby on a high after securing UEFA Champions League group stage qualification against Lyon, though key duo Mattéo Guendouzi and Mason Greenwood await potential UEFA disciplinary rulings following post-match incidents in France. Domestically, Vedat Muriqi and Oğuz Aydın scored in a comfortable 2–0 win over Samsunspor last week.
Beşiktaş, meanwhile, put on a masterclass in Matchday 3, crushing Çorum FK 6–1 at Tüpraş Stadium. New signing Dušan Vlahović has hit the ground running with 3 goals in 3 games, while central midfielder Fabio Miretti controls the tempo. However, the Black Eagles missed out on finalizing a late deal for Rangers midfielder Nicolas Raskin after negotiations collapsed.

Venue: Kazım Karabekir Stadium, Erzurum
Erzurumspor earned a solid 1–1 draw away to Gençlerbirliği last week to pick up their first point of the campaign. Returning home to altitude, they host a Konyaspor side that suffered back-to-back defeats against Fenerbahçe (4–2) and Kocaelispor (2–1). Both teams struggle defensively, making goals a likely outcome in eastern Anatolia.
Prediction: Erzurumspor 1–0 Konyaspor
Kasımpaşa vs Amed SK
Kickoff: Sunday, September 6, 15:00 BST / 17:00 Local
Venue: Recep Tayyip Erdoğan Stadium, Istanbul
Amed SK delivered the shock of Matchday 3 by defeating Trabzonspor 2–1 in Diyarbakir, thanks to a 90th-minute winner from substitute Gift Orban. Dia Saba and Yira Sor provide genuine transition threat. Kasımpaşa have been stubborn, recording a 1–0 win over Çorum and a 1–1 draw at Başakşehir.

Trabzonspor vs Gençlerbirliği
Kickoff: Sunday, September 6, 18:00 BST / 20:00 Local
Venue: Şenol Güneş Sports Complex, Trabzon
Tensions are high in Trabzon following the resignation of manager Fatih Tekke after their 2–1 loss to Amed SK. Despite marquee signing Mohamed Salah opening the scoring (his 3rd goal in 3 games), the Black Sea Storm look disjointed defensively. Pundits have urged the board to consult Salah regarding the club’s next managerial appointment.
They face a surprise Gençlerbirliği side that sits second in the table on 7 points, having already shocked Fenerbahçe on opening weekend. Trabzonspor cannot afford another slip-up at home.

Promoted Kocaelispor have taken the Süper Lig by storm, winning two consecutive matches against Amed SK (2–0) and Konyaspor (2–1). Powered by strong home support, they face a Samsunspor side licking their wounds after a 2–0 home loss to Fenerbahçe.

Göztepe vs Gaziantep FK
Kickoff: Monday, September 7, 18:00 BST / 20:00 Local
Venue: Gürsel Aksel Stadium, İzmir

Prediction: Göztepe 2–1 Gaziantep FK
