According to Sky Sports, Atletico Madrid are keen on signing the left-back, who has also been tracked long-term by their sporting director Mathieu Alemany. Alemany is said to have admired Cucurella during his time at Barcelona, and remains a strong supporter of a potential move.
Cucurella is considered an important first-team player at Chelsea, but with just two years remaining on his current deal, his future is starting to come under scrutiny. If no new contract is agreed, Chelsea could be open to a sale under the right conditions.
Barcelona are also monitoring the situation closely, although their transfer priorities appear to be shifting. The Catalan club are working on making Joao Cancelo's loan move permanent and are expected to focus much of their budget on signing a new striker following the departure of Robert Lewandowski.
Atletico, meanwhile, are expected to remain active in the chase, setting up a potential summer battle between the two Spanish rivals.
Barcelona's striker target is believed to be Julian Alvarez, a move that could also influence other deals involving players such as Marcus Rashford, who is keen to stay at the club after his loan spell.
For Chelsea, the situation leaves Cucurella's future open but unresolved. With momentum building under incoming coach Xabi Alonso, the defender may yet choose to stay in London, though contract talks will be key in determining what comes next.
