Chelsea striker Diego Costa has never shied away from the fact that he misses his Atletico Madrid days but there is one particular facet he yearns for more than most.
The Spain international, who made his name at the Vicente Calderon before moving to Stamford Bridge, spoke to Spanish media earlier this week and was asked what he missed most about playing for Diego Simeone's team.
Costa revealed his duels with Real Madrid defenders Sergio Ramos and Pepe in the feisty city derby is up there, saying a battle with two world-class defenders was a challenge he used to cherish.
