David Luiz will serve a three-match ban for the red card issued in Chelsea's 0-0 draw with Arsenal but Graeme Souness thinks the defender got off lightly.
The Blues centre back was dismissed by referee Michael Oliver for a reckless challenge on Sead Kolasinac late on.
Souness described the challenge as a 'red card plus' and suggested that Luiz should have been sent off earlier in the second half for another count of dangerous play.
Luiz was shown a yellow card on 52 minutes after he attempted to score with an overhead kick but instead caught Laurent Koscielny in the face.
