Bayern Munich coach Jupp Heynckes had no problem with Arsenal manager Arsene Wenger failing to shake hands at the end of last night's game.
Clearly upset by the result, Wenger headed straight down the tunnel without shaking Heynckes's hand.
Heynckes said: "We met before the game and we know each other well. I've known him for years and we have a good relationship."
He added: "Arsenal are a good team and we will take the second leg seriously. We can't afford to underestimate them."
