Manchester City's FA Cup journey against Luton took a bittersweet turn as Jack Grealish suffered a fresh blow with an injury setback. The winger's anguish was palpable as he was forced off the field during the fifth-round clash at Kenilworth Road.

Grealish's distress was evident as he broke down on the pitch, receiving solace from his concerned teammates. The untimely injury forced Pep Guardiola into an early substitution, with Jeremy Doku stepping in for the injured star after just 38 minutes of play.

Cameras captured the emotional moment as Grealish, draped in a training jacket, sought refuge before being comforted by his fellow players. Despite his visible disappointment, Grealish acknowledged the support of the traveling Manchester City fans as he made his way off the field at halftime.

Guardiola provided an update on Grealish's condition post-match, indicating a possible groin injury and expressing sympathy for the player's challenging season marked by fitness setbacks. Indeed, Grealish's contributions have been marred by spells on the sidelines, including a previous hamstring issue earlier in the campaign.

The setback against Luton adds to Grealish's woes, disrupting his return to action after a recent absence from the matchday squad. However, Manchester City found solace in Erling Haaland's remarkable performance, as the Norwegian striker's first-half hat-trick propelled them to a commanding 6-2 victory in the FA Cup encounter.

Manchester City's depth and resilience shone through despite the setback, showcasing their ability to overcome adversity despite key injuries. As they progress in the FA Cup and various other competitions, Guardiola and his squad will be hopeful for Grealish's swift recovery, knowing his impact on the team's success is significant.
