Bayern Munich will use the first leg of their Champions League last-16 match against Arsenal tonight (7.45pm) as a barometer of the team's progress this season, coach Pep Guardiola said.

The Champions League holders defeated their English opponents 3-1 in the same stage of the competition at the Emirates last year.

"It's a good test for us. We will know what our level is in Europe this year," Guardiola told a news conference.            

"You can't dominate for 90 minutes against Arsenal, it's impossible. You can play good and maybe dominate one half or 75 minutes but never the full game. With their quality of players you can always have problems.            

"We won't think about the second game, we're just concentrated on what we have to do."

Bayern have lost only once in 34 games and have won 13 successive Bundesliga matches but Guardiola wants to guard against the complacency that caused the eventual champions to lose 2-0 at home in the second leg against Arsenal 12 months ago.

"We have to accept that every game we are favourites and that we are favourites to retain the title, I can't deny that," he said.

"I'd like to live without these feelings but I can't. But [tonight] we start 0-0," Guardiola added.

"Always with the ball they (Arsenal) are organised and in good shape. Once we let them (have) the ball we will suffer. We must dominate the ball."
