The Real Madrid coach is fancying a move for the Chelsea left back.
The club is trying desperately to bring in new recruits before the transfer window closes in two weeks time.
Real Madrid have allowed some quality players to leave in the past window without bringing in replacement. Now, it's telling on the club.
Theo Hernandez was allowed to join Real Sociedad on loan and now they need to sign another player.
Lopetegui has been a fan of the Chelsea player. He even called him to feature in his world cup team. However, the player is an important one for Chelsea and the club will do everything possible to hold on to their man.
