Kai, the 16-year-old son of the legendary Wayne Rooney, is preparing for what could be a pivotal season with Michael Carrick confirmed as the club's new permanent boss in May. Despite fierce competition for places in forward positions, it seems he is relishing the challenge. The youngster shared an enigmatic photograph on social media on Tuesday, which left supporters both puzzled and thrilled in equal measure. Posted to his Instagram Stories, Rooney's picture appeared to show a man flexing his bicep in the gym. Supporters were split over whether it was him in the snap or somebody else altogether, before Kai subsequently confirmed in a later post that it was, in fact, him. That prompted even greater enthusiasm from the United supporters, who are becoming increasingly animated about the talented forward's prospects. One supporter wrote on X: "Kai Rooney will be the only player to ever match/surpass his father's superstar status, records, and achievements in football history." Another commented: "Damn how did we get from this to that in three months, this kid wants to oppress defenders like his father did." Rooney was sidelined for the closing months of the 2025/26 campaign following his Under-18s debut in January. With considerable time away from the pitch, it seems he may well have been dedicating hours in the gym to build his physique. Given his age, it would come as no shock if he were looking to add muscle ahead of a potential Premier League breakthrough next term. Carrick is fully aware of Rooney's ability and would have observed him closely, having progressed through the same youth set-up as his son, Jacey. The United manager has been seen assessing the Under-18s last season, and he may be prepared to offer him an opportunity to shine in domestic cup competitions next season. He could shortly follow in the footsteps of the likes of Shea Lacey in making the step up to the first team, alongside United prodigy JJ Gabriel. Young Kai has missed the opportunity to become United's youngest-ever player, as he has exceeded the age of the club's youngest footballer on record, David Gaskell. That record has remained intact since 1955 despite United's tradition of promoting academy graduates. However, he could still carve his name into the club's history books as their youngest in the Premier League era. That distinction currently belongs to Shola Shoretire, who featured in the 2020/21 season at the age of 17 years and 19 days. He could surpass his father's record from 24 years ago, which launched him into the spotlight. Rooney Snr. famously made his Everton debut aged 16 years and 297 days old, scoring the winner against Arsenal back in August 2002. Kai can make his bow 12 days earlier than that if he features on the opening day of the Premier League season in mid-August. Even if he fails to persuade Carrick before then, United supporters are clearly excited by the possibility of another member of the Rooney family appearing at Old Trafford.
