Arjen Robben has stated his belief that Borussia Dortmund will give Bayern Munich a "good battle" when the German giants lock horns on Saturday.
The veteran forward spoke to the official Bundesliga website ahead of the top-of-the-table clash at the Allianz Arena, and admitted that Die Borussen would be a formidable foe to overcome.
Bayern and Dortmund matches have been tasty affairs in the past 10 years as the latter became a force in German football, and Robben expects nothing else from a side that has purred under new boss Peter Bosz so far this season.
He said: "It's always a good battle between both teams. I've been at Bayern for eight years now, this is my ninth season.
"When I first moved here they were not challenging at the top of the league, but now they are. It's always very competitive and there have been a lot of great games in the past.
"They have always been physical, strong and aggressive. They are dangerous on the counter attack. They have a lot of pace in their team. But they are playing differently I think, they turn defence into attack very quickly.
"Peter Bosz wants them to win the ball back within only a few seconds of losing it. That's what he asks of his team."
Bayern themselves installed a new manager in their dugout this term when legendary head coach Jupp Heynckes returned to replace the sacked Carlo Ancelotti in October.
Asked about his relationship with his new gaffer, Robben explained that he was happy to work under Heynckes again and backed the 72-year-old to help steer Bayern to yet more title glory in 2017/18.
He added: " [Our relationship is] very good, we have obviously already worked with each other. Several other players know him well so we know how he works, what he demands from his team as a team but also as individual players.
"It's important that he knows the team, he knows how the team works and that is exactly what we need at the moment."
