Celtic and Brighton have reached a deal in principle for midfielder Matt O'Riley, marking a record transfer fee for a Scottish club at up to £30 million, including add-ons. The agreement follows multiple failed bids from Atalanta and reflects O'Riley's impressive performances, including 19 goals and 18 assists last season. The 23-year-old Denmark international is expected to miss Celtic's upcoming match as he finalizes the transfer. This deal is seen as beneficial for both clubs, with Celtic receiving a significant financial return on a player they acquired for just £1.5 million in 2022. Experts believe O'Riley could thrive in the Premier League, potentially increasing his market value further. As negotiations continue for new signings, Celtic is eyeing Mateusz Bogusz as a replacement for O'Riley.
