Villareal defender Pau Torres is the latest name to appear on the Chelsea radar.
He was heavily linked with Manchester United in the summer, before they turned their attention to Raphael Varane, and played for the Spanish club in their defeat at Old Trafford in the Champions League on Wednesday night.
Chelsea meanwhile spent the summer pursuing Jules Koundé of Sevilla, and, although they were unable to agree a valuation for him,. the Frenchman remains a person of interest for the West London club.
However, as they continue to look for defensive reinforcements, Torres is another man currently playing In La Liga who they are tracking.
The 24-year old is highly regarded in Spain and played for the national team both inn the Euros and at the Summer Olympics.
He is under contract with his current club until 2024, and his current market value is estimated at €50 million (£43 million).
