Chelsea are pursuing a transfer for a Real Madrid outcast this summer as part of their squad revamp.
The Blues are determined to give new boss Mauricio Pochettino the tools to succeed.
Per Mundo Deportivo, one of their surprise targets is Alvaro Odriozola of Real Madrid.
The 27-year-old played only 92 minutes for Real throughout the past season.
He is unhappy at the club, with the ex-Real Sociedad man wanting to move on to another team.
Odriozola does not have a preference of club, but would rather choose a team where he will play regularly.
Real Sociedad are also interested in bringing him back to the club, while Chelsea are ready to swoop.
