Manchester United midfielder Kobbie Mainoo has yet to make a single start in the Premier League this season, making only ten substitute appearances for a total of 183 minutes. Despite this, there are reports that Barcelona are interested in signing the midfielder, potentially reuniting him with Marcus Rashford.Barcelona's efforts to secure Mainoo's transfer are likely to be challenging, as other clubs are also interested in the player. These clubs include Napoli, Chelsea, and Real Madrid, which could make it difficult for Barcelona to secure a deal.
