LEICESTER -- Chelsea showed that they have the quality to win without Diego Costa against Leicester City, according to Thibaut Courtois.
A double from Marcos Alonso and a Pedro Rodriguez goal secured a 3-0 win for Chelsea at the King Power Stadium despite being without Costa, who did not travel with the squad.
After the match Antonio Conte insisted that Costa's absence was due to a back injury, but sources told ESPN FC on Friday that the 28-year-old trained alone at Cobham for three days last week after a heated argument with a Chelsea fitness coach and Conte.
