Arjen Robben has warned his Bayern Munich team-mates they will have to step up their game if they are to beat Arsenal in the Champions League.
The reigning Bundesliga champions beat Freiburg and Werder Bremen in their first two games after the mid-season break, but were far from convincing in those performances.
“I think it is going to be very tough,” Robben told TZ.
“It will be very difficult against Arsenal if we do not improve. We still have plenty of work to do, but we are all well aware of that.
“We have to be calmer, more organised and have more control. We have to improve in all those areas. We must make things easy for ourselves again.”
The first leg is scheduled for February 15 at the Allianz Arena, with the return at the Emirates Stadium taking place on March 7.
