The forward praised Arsene Wenger's side and thinks the Gunners are the most difficult opponent the Bavarians could have faced in the Champions League
Arsenal, which finished second behind Borussia Dortmund in the group stage, hosts the reigning European champions in the first leg of their last 16 tie February 19.
While Muller believes Wenger’s men will provide a difficult test for Bayern, the forward believes the German club’s dominance over the last few seasons gives it the edge.
"The Gunners play a very beautiful football, they are the most difficult opponent we could have got," Muller told Kicker. "We are on eye-level with this top team from the Premier League.
"We have had more success on national and international level than Arsenal in recent years, that's why we are slight favorites. We are the holders and we have improved. Of course, we are the team to beat when it comes to the [Champions League] title."
