Chelsea have now conceded 18 goals in their last eight games in all competitions. The absence of Terry with a knee injury for three weeks after only just returning from a four game domestic ban has added to their woes ahead of Tuesday’s away Champions League clash with Juventus.
Di Matteo said: “Clean sheets certainly give you a chance to win games and we have to improve on that side. Defensively we just weren’t good enough. Of course we miss John (Terry). He is an important player and gives us a lot of confidence at the back, but we will have to do without him until he comes back.”
