Bayern Munich boss Pep Guardiola believes that the Champions League tie with Arsenal will be a barometer for how far his team go in the tournament.

The reigning champions face the Gunners at the Emirates Stadium tomorrow for the first leg of their last-16 clash.

The Spaniard has failed to beat Arsene Wenger's men in North London on two previous occasions with Barcelona, and Guardiola does not expect his team to boast a healthy aggregate lead heading into the second leg on March 11.

"You can play good, you can dominate during half-time, 30 minutes, 75 minutes, but complete 90 minutes it's impossible. Always you have a problem," he told a press conference.

"We'll try to make a good game, as best as possible; don't think too much about the second game, concentrate on what we have to do tomorrow. And I hope it goes well.

"It's a good test tomorrow to know what is our level in Europe this year.''

Tomorrow's encounter kicks off at 7.45pm.
