Chelsea are stepping up interest in Atletico Madrid fullback Nahuel Molina.
The Blues are seeking a new fullback signing for the January market and have expressed interest in Inter Milan defender Denzel Dumfries.
TMW says Argentina international is also under consideration after impressing management at the World Cup.
Chelsea have been tracking Molina since his time with Udinese.
However, it is also understood that Dumfries remains Chelsea's priority target.
