Bayern Munich have failed to make a breakthrough despite dominating a goalless first half against Borussia Monchengladbach.
Gladbach were the first side to create an opening when they attacked at pace through Raffael, but the Brazilian could only fire his effort straight at Manuel Neuer.
Bayern soon took control of the game but they were up against a goalkeeper in fine form as Yann Sommer made saves to deny Robert Lewandowski and Thomas Muller.
The deadlock should have been broken just moments later when Xabi Alonso's free kick found Mehdi Benatia, whose tame header was easily stopped by Sommer.
A breakthrough for the visitors looked inevitable as they continued to pile the pressure on, with Kingsley Coman coming agonisingly close to an opener when he rattled the post with a powerful strike.
