AZ Alkmaar vs Celtic: What has been said?
Celtic boss Ange Postecoglou: "That's the best approach for us, as if we go there and try to defend for 90 minutes, I just think you're asking for trouble.
"They are a good team and we know at home they're going to be playing fairly high-tempo and high-intensity football to score goals, so if we sit back, we are just going to invite pressure on ourselves.
"I was disappointed we didn't get through to the Champions League first stage, and this is the next opportunity for us to guarantee ourselves some opportunities for some big European nights, to take on some of the biggest clubs in Europe.
"So it's not an end-all, it's more that this gives us an opportunity to try to build something special for this year and beyond, so it's an important fixture because of that, and the players are looking forward to that sort of contest where you know that if you get through it, then that opens up more possibilities to do something special.
"That is the responsibility, but also the beauty of playing for this football club.
"Every game is an opportunity to do something special and certainly tomorrow night we will get that platform to play in a big game, for the players to showcase their talent and for us as a team to keep progressing and evolving into the team we want to be."
