Filipe Luis joined Chelsea alongside fellow Atletico Madrid star Diego Costa in 2014 and the pair won the league title during their opening season at the club.
Eden Hazard was crowned PFA player of the year that season but Luis has insisted Costa – who also recently rejoined Atletico – is the best player he’s played alongside and not Hazard.
“Costa is the best I have played with,” Luis told El Mundo.
“I have seen [Juan Carlos] Valeron do things nobody could do. Neymar and [Eden] Hazard are amazing talents, but the player who gave me most trophies was Diego Costa.
“He always scores the opening goal. Because it is one thing to score 30 goals with hat-tricks in easy wins, and another that 20 of those 30 goals are enough to win 1-0. Nobody does that as well as Diego Costa.”
Luis spent one season at Stamford Bridge before returning to Diego Simeone’s side in 2015.
