Chelsea star Kalidou Koulibaly proved many people wrong by putting in an excellent defensive display for the Blues in their Champions League round of 16 clash against Borussia Dortmund on Wednesday. After signing from Napoli in the summer, Koulibaly has struggled for consistency and the arrival of Benoit Badiashile in January saw him lose his spot in Graham Potter's starting XI.
During his first few months as a Chelsea player, Koulibaly was often deployed on the left of a back three with Potter opting for a similar shape to the one that brought him so much success at Brighton. However, those fortunes were not repeated in west London and Potter therefore shifted to a back four which has seen Badiashile partner Thiago Silva for the last four Premier League games.
Across those 360 minutes played together, the duo have conceded just one goal helping Chelsea keep clean sheets against Liverpool, Crystal Palace and Fulham. Their form meant the likelihood of Koulibaly coming back into the team was low, however the Champions League presented a major opportunity for the 31-year-old.
