Victor Osimhen marked his return from injury with a goal as Galatasaray dismantled rivals Fenerbahçe 3-0 in a derby clash that exposed glaring weaknesses.

Fenerbahçe had the chance to seize control early but squandered a penalty in the 13th minute, as Anderson Talisca’s miss proved to be a turning point that shifted momentum entirely.

Galatasaray capitalised ruthlessly, with Osimhen opening the scoring in the 40th minute, punishing defensive lapses to give his side a deserved lead heading into the break.

The contest effectively ended when goalkeeper Ederson was sent off in the 62nd minute, leaving Fenerbahçe reduced to 10 men and unable to cope with the mounting pressure.

Barış Alper Yılmaz converted from the penalty spot just five minutes later, further exposing the visitors’ defensive disarray and lack of discipline.

Lucas Torreira sealed the emphatic win in the 83rd minute, capping off a dominant display that highlighted Galatasaray’s superiority in both composure and execution.

The result keeps Galatasaray top of the table, while Fenerbahçe are left to reflect on costly errors that continue to derail their title ambitions.
