Bayern Munich star Thomas Muller claims Arsenal are the "most difficult opponent" to face for the treble winners.

The Champions League holders face the Gunners in the knockout stages of the European competition. The first leg will be held at the Emirates on 19 February before Arsene Wenger takes his men to Germany for the second leg in March.

The two teams faced each other in the Champions League knockout stages last year. Bayern had a comfortable 3-1 victory at the Emirates while the second leg at the Allianz Arena saw the Gunners register a 2-0 victory.

Despite Arsenal's victory in Germany, Bayern knocked the north London club on away goal rules. The Bundesliga outfit went on to win the competition last season and Muller claims his side are still favourites to win this term.

"The Gunners play a very beautiful football, they are the most difficult opponent we could have got. We are on eye-level with this top team from the Premier League," Muller told Kicker

"We have had more success on national and international level than Arsenal in the last few years, that's why we are slight favourites. We are holders and we have improved. Of course, we are the team to beat when it comes to the [Champions League] title," the German international added.

Meanwhile, Arsenal's star player in their 2-0 victory over Crystal Palace Alex Oxlade-Chamberlain has set his sight on scoring more goals for the north London club. The England international struck twice on Sunday at the Emirates as the Gunners sealed three points against Palace.

Wenegr deployed Chamberlain in the central midfield position after Aaron Ramsey was sidelined due to injury.

"It's always an amazing feeling to score a goal, especially at a superb stadium like the Emirates. I'm glad to give something back to the fans. It's something that I want to add to my game more so it was nice to get two today," Chamberlain told Arsenal's official website.

"To play in midfield was nice. It's nice the boss has faith in me there. It's nice playing in midfield with players like we have, when we have got a lot of the ball."
