Unconfirmed reports suggest that negotiations over the transfer of Axel Disasi are ongoing, with Crystal Palace pushing to land the defender from Chelsea to strengthen their squad. Discussions are said to be constructive, with the structure of the deal - including add-ons and bonuses - now under consideration, although there is currently no confirmation of an agreed fee for the player. The player is aware of the interest and would reportedly be open to the move, should personal terms be agreed. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Aston Villa, Monaco and West Ham decide to make a formal offer of their own in the coming days. With only 5 goals conceded in 7 (0.71 per game), Crystal Palace have been one of the stronger defences in the Premier League this season.. Axel Disasi would be asked to keep that standard and provide dependable cover when needed. Alongside this, Chelsea are said to be exploring Conrad Harder, Roger Fernandes and Ademola Lookman with Crystal Palace likewise connected to Joe Gomez, David Brooks and Christoph Baumgartner.
