Thibaut Courtois says Chelsea must show more bite in front of goal. Antonio Conte's Blues were held to a goalless draw in Wednesday night's League Cup semi-final first leg with Arsenal. They also failed to score at Norwich on Saturday, prompting an FA Cup third-round replay next week. "Against Stoke we scored five goals but against other teams we have maybe missed too many chances," Courtois said.
