Borussia Dortmund may have enjoyed a strong start to the 2018-19 season but Manuel Neuer has not ruled out Bayern Munich catching the Bundesliga leaders.
Dortmund hold a six-point advantage at the top of the table having won 14 of their 18 matches, losing just once.
In contrast, Bayern have struggled for consistency at times, enduring tough spells in September and November – the latter including a 3-2 defeat to Dortmund.
