Erling Haaland scored both goals as Manchester City defeated FC Porto 2-0 in their Champions League opener, reinforcing his critical role for the club. The 26-year-old Norwegian striker moved into third place in City's all-time scoring list with 167 goals and matched Sergio Aguero's record of 36 Champions League goals for the club. His overall Champions League tally now stands at 59, surpassing Thomas Müller to rank seventh in the competition's history.

Haaland has scored 304 goals in 390 club games since his professional debut at 16 with Bryne. His five goals in five games this season highlight his consistency, but City's lack of a recognized centre-forward backup raises concerns. With Omar Marmoush's departure to Tottenham, manager Enzo Maresca has limited options to replace Haaland, relying on wingers or midfielders like Phil Foden in central roles.

While Haaland has missed only 23 games in four seasons since joining City, his heavy workload across competitions raises questions about sustainability. The article notes that without Haaland, City's title ambitions would face significant challenges, underscoring his irreplaceable impact despite the tactical vulnerability his absence creates.
