Atletico Madrid could be blocked in their summer push to sign the Celtic star Matt O'Riley.
Los Rojiblancos are planning squad updates ahead of the 2024/25 season with midfield a key area of focus for Diego Simeone.
The club continues its policy of selling and releasing players to raise transfer funds and free up space on its inflated salary list.
Celtic playmaker O'Riley has been a target for Simeone for the past 12 months but Atletico Madrid has not matched Celtic's valuation so far.
Despite confidence in Madrid that a deal can be reached, Celtic are determined to keep the Denmark international in Glasgow, and will now increase their asking price.
According to the latest reports from AS DiaryCeltic could demand €40m for the 23-year-old, ie Saul Niguez I would need to leave.
Even if Saul agrees to terminate his contract, a lower fee will be presented to Celtic as Atletico Madrid aim for a structured deal.
