Borussia Dortmund coach Jürgen Klopp insists his side have only themselves to blame for their 3-0 Champions League defeat to Marseille on Wednesday.
In a game dominated by Dortmund, it was the French side who were more clinical as a brace from Andre Ayew and a Loïc Remy goal were enough to send them top of Group F.
Speaking after the match, Klopp bemoaned his side' defensive frailties which cost them dearly.
