Bayern Munich coach Heynckes shrugs off Wenger handshake snub
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."
