Chelsea have joined Roma and Villarreal in the battle to sign Real Madrid central defender Nacho, Spanish website AS has reported.
The 26-year-old has struggled to secure a regular place in Zinedine Zidane's side last season.
He is one of the many players linked with a move to Stamford Bridge to strengthen the Chelsea defensive department.
Meanwhile, reports from Italy have confirmed that Leonardo Bonucci is a target for new manager Antonio Conte.
The Juventus man could leave the Serie A in the summer and he would be ready to again work under the Italian manager.
