Bayern Munich boss Pep Guardiola believes his players must put in an exceptional performance at Arsenal on Wednesday if they want to win.
The Bavarians face the Gunners in the last 16 stage of the Champions League for a second successive season, having knocked out Arsene Wenger's men on away goals a year ago.
With Jupp Heynckes' ultimately successful side having lost 2-0 at the Allianz Arena in the return leg in 2012-13, Guardiola is wary of cutting it so fine again, but says it will be impossible to dominate the entire first leg at the Emirates Stadium.
"Tomorrow we need an exceptionally great performance," the Spaniard told reporters. "My goal is always for us to perform better than last time.
"I learned from the past you can never dominate for 90 minutes against Arsenal. When we give the ball to them, we are going to suffer. Tomorrow the most important thing will be to dominate the ball.
"We'll need to monitor Mesut Ozil and that will work best if we keep hold of possession."
Guardiola hopes it is third time lucky at the Emirates Stadium and heaped praise on the influence of club captain Philipp Lahm, whom he has converted from a fullback to a defensive midfielder this season.
"This is my third time here and I've still not won," he added. "We need to create chances and score an away goal. Otherwise you have no chance in Europe.
"Without Lahm we would not be here, he is one of the most important Bayern players in history."
