Pep Guardiola says it's "impossible" to dominate Arsenal for 90 minutes.
The 43-year-old Spaniard will be looking for his first win at Emirates Stadium on Wednesday when his Bayern Munich side take on the Gunners in the Champions League.
Bayern have lost just once this season and are 16 points clear at the top of the Bundesliga, but Guardiola believes he will know more about his side's level after Wednesday's game.
If you look at Arsenal, with these quality players, you always have a problemPep Guardiola
"I learned that you can never dominate Arsenal for 90 minutes," Guardiola said. "You can dominate for 30 minutes, to half-time, for 75 minutes, but for 90 minutes it is impossible.
"If you look at Arsenal, with these quality players, you always have a problem.
"We are in the most prestigious competition in world football and in a perfect setting - here at Arsenal, in London - so it’s a good test for us.
"We are doing well in Germany, but now we face a good test to know what our level is. I’m looking forward to finding out."Copyright 2015 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source
