Chelsea are ready to rival Manchester City in their chase to sign Valencia star Jose Gaya during the January window, according to reports from the Express.
The 20-year-old was also being monitored by the Premier League champions during the summer, but were more focused on luring Everton centre-back John Stones to the club.
City are also being linked with the services of the left-back who only signed a contract to keep him at the club until 2020 last year.
Apart from the two English giants, Real Madrid are also believed to have been keeping an eye on the player, but pulled out when he eventually decided to extend his stay with their league rivals.
Blues boss Jose Mourinho could be looking to make some changes to his side after experiencing a nightmare start to their current league campaign.
He has already lost three out of his first five fixtures this term as he now prepares his side to face Maccabi Tel Aviv in the Champions League group stages tonight.
