Manchester City fans, breathe a sigh of relief! Manager Pep Guardiola has received a major fitness boost just in time for the Premier League's blockbuster showdown this Sunday.

The news centers on young star Nico O'Reilly, who was substituted during last weekend's victory over Chelsea. Guardiola has confirmed O'Reilly is "fine" and available for selection against league rivals Arsenal. This is a significant development, as O'Reilly has become a key figure in City's midfield and famously scored a brace against the Gunners in last month's Carabao Cup final.

His energy and goal threat—with nine goals across all competitions this season—will be vital in a match that could have huge implications for the title race.

However, the update wasn't all positive. Guardiola also revealed that defensive stalwart Ruben Dias is "not ready" for the fixture. The absence of the experienced center-back will test City's defensive depth as they prepare to face one of the league's most potent attacks.
