Chelsea started negotiations with 24-year-old Spain international

London club already planning their next round of transfers with ban ready to expire at the end of the campaign if the appeal fails. Blues have identified left-back as one of the positions to bolster when their transfer ban expires.

Chelsea are unable to sign new footballers until next summer but have launched an appeal to the Court of Arbitration for Sport to have the embargo lifted by winter. A raft of arrivals are expected whenever their suspension ends, and work is ongoing behind the scenes.

Valencia left-back Jose Gaya is one of the footballers under consideration. Spain international is one of La Liga top talents and has represented his country six times. Blues have held negotiations over a potential swoop for the attacking full-back.

Jose, who has played 197 matches in all tournaments for the Bats, could replace Marcos Alonso, who finds himself out of favour under English manager. Marcos has managed only one minute of action, having lost the left-back role to Emerson Palmieri.

Alonso could get his opportunity against Wolves on the weekend after Emerson suffered an injury while on international duty with Italy. London club blocked an attempt from Atletico Madrid to sign Spaniard in the transfer window.

Chelsea vetoed a potential departure because of their inability to source a replacement due to their transfer ban. The 28-year-old defender has featured 121 times for the Blues since leaving Fiorentina behind in 2016, scoring 18 goals. He played a crucial role in their 2016/17 Premier League title triumph under Antonio Conte, netting seven times.
