Marc André Ter-Stegen has cast doubt on the mentality inside the Barcelona dressing room.

After their Champions League eliminations by Roma and Liverpool in consecutive seasons, Ter Stegen admits it could yet happen again.

He told 11Freunde: "They cannot be clarified by tactical or game errors but one must dive deeply into matters of psychology.

"I would never say that this cannot happen to us again."

Ter Stegen's quotes arrive in the same week he called for a squad meeting after their battling Champions League win at Slavia Prague.
