"I'm lucky to be here [at the Allianz Arena] for my first Bundesliga game, and I hope it won't be my last!
"I think to myself before every game that it's going to be very, very dangerous, and I know this one's going to be a very, very dangerous game."
Guardiola has spent a year out of the game since leaving Barcelona.
