Fermin has already been approached by Manchester United this summer, but Chelsea are now also keen on acquiring his services. However, any potential move to Chelsea will depend on the club being able to free up space in their wage budget. This could involve selling several key players, which would make room for new signings.
Fermin himself is reportedly hesitant to leave Barcelona. The Catalan club, however, wishes to sell him as they need to create space to meet LaLiga's financial regulations. This is in order to register their new signings, including Roony Bardghji.
Chelsea's ability to sign Fermin will also depend on their negotiations with other clubs. They will need to either fail to agree on terms with Manchester United for Alejandro Garnacho or with RB Leipzig for Xavi Simons.
