Thomas Muller believes Borussia Dortmund remain Bayern Munich's biggest competitor for the Bundesliga title despite their 2-0 defeat against Bayer Leverkusen on the opening day of the season.

Leverkusen's 2-0 win at Dortmund's Westfalenstadion was the result that stood out last weekend as Bayer outplayed last year's Bundesliga runners-up.
However, Bayern attacker Muller believes that the starting position in the race for the Bundesliga has not dramatically changed.
"Essentially, I still regard Dortmund as our biggest competitor," Muller told Bild. "They know how to win titles. And they always keep their cool."
Muller did also recognise that Leverkusen could be contenders, adding: "In the past few years, Leverkusen have always played a good role, and they will surely do so again this season."
In 2010-11, Leverkusen were the last team to end the season between Bayern and Dortmund, finishing second behind BVB during Jupp Heynckes' final season in charge at the BayArena.
Three years on and three coaches later -- Robin Dutt, Sascha Lewandowski and Sami Hyypia -- forward Stefan Kiessling has been one of the few constants at Leverkusen.
The veteran attacker impressed against Dortmund and believes that Leverkusen should be aiming high.
"I have been here for nine years. I want to win the title," he told Sport Bild. "But everything needs to work out over 34 match days."
