Manchester United fans have been left excited after academy graduate Kobbie Mainoo was named in the starting XI against Brighton & Hove Albion. The Red Devils are set to lock horns with the Seagulls in their FA Cup Third Round meeting as they hope to keep hopes of silverware alive. Stand-in head coach Darren Fletcher is set to take charge of his second match in interim capacity, having overseen a 2-2 draw with Burnley in midweek. He made three changes to the XI that earned a point at Turf Moor with a place in the next round of the cup on his mind. England international Mainoo has been restored into the XI, making only his second start for the club this season. His only other start came in the shock defeat to Grimsby Town in the Carabao Cup while Ruben Amorim was in charge of the side back in August. The inclusion of Mainoo in the XI has been met with palpable excitement from the Manchester United faithful owing to the quality he has shown in his career so far. A section of the club's fans took to X to express their delight at the midfielder's inclusion.

Shaw was not named in a matchday squad for the first time since August, when he was rested for the Grimsby game. Mainoo was set to be on his way out of the club after failing to feature regularly under Amorim. The sacking of the Portuguese tactician may prove to give the 20-year-old a new lease of life at his boyhood club.
