Bayern Munich has taken a 1-0 lead at half-time in the first Bundesliga Der Klassiker of the season.
Robert Lewandowski opened the scoring in the 17th minute to continue his scoring streak in the Bundesliga this season.
Gnabry's cross from the right was initially cut out but bounced back to Pavard who was wide on the right. He passed the ball to an unmarked Lewandowski who heads in his 15th league goal of the season.
That goal saw Lewandowski become the first player in Bundesliga history ever to score on each of the first 11 games of a season. His tally of 15 goals after 11 matches also puts him on equal record set by Gerd Muller in the 1968/69 season.
Ten minutes after the first goal, Lewandowski was afforded plenty of time and space inside the box, he found Coman but his shot was cleared off the line by Hummels.
Dortmund made an early substitution with less than 10 minutes to the end of the first half, taking off Sancho for Guerreiro.
Just after the sub, Gnabry's saw his goal disallowed. Davies delivered a brilliant ball from the left straight to the feet of Lewandowski, whose first-time shot took a deflection off a defender and falls to Gnabry who tapped into the empty net. However, referee Felix Zwayer ruled the goal offside.
Dortmund got their best chance just before the sound of the half-time whistle when Guerreiro delivered an in-swinging free-kick from the right towards the back post. It was high and just too long for Witsel who could not get any direction on the ball.
It's Bayern leading 1-0 after 45 minutes at the Allianz Arena.
