Manchester City's crucial Premier League title clash with Arsenal this Sunday may have to proceed without a key contributor, as Nico O’Reilly faces a race against time to be fit. The left-back, who has been in fine form, was forced off during City's weekend victory over Chelsea with a concerning hamstring issue.

O’Reilly pulled up in the 64th minute, visibly holding his right hamstring before being substituted. While the exact severity is still being assessed, any strain could sideline him for several weeks, casting significant doubt over his availability for the weekend's blockbuster fixture.

This potential absence would be a major blow for City. O’Reilly has become a clutch performer, notably scoring against Arsenal in the League Cup final and opening the scoring in the recent win against Chelsea. His potential loss adds a layer of intrigue to an already monumental match.

The stakes at the Etihad Stadium couldn't be higher. A win for Arsenal would see them open a commanding nine-point gap at the summit. A City victory, however, would essentially wipe out the Gunners' advantage and swing the momentum of the title race decisively back towards the champions. Every player available will be critical in such a high-pressure environment.

All eyes will now be on O’Reilly's recovery. The hope for City will be that further examination reveals only minor tightness, giving the defender a fighting chance to suit up for a game that could define the season.
