Aberdeen manager Derek McInnes: "We feel ready for it.
"We felt ready for it last week and we're certainly ready for it tomorrow.
"We're not prioritising one competition over the other. We know the financial rewards for getting through this tie and hopefully beyond. We want to do well in all competitions.
"You have to adjust as the game unfolds but the fundamentals being you still need to stop good players having time to play.
"When good players have time on the ball as they have, it can be a problem.
"We just want to make sure we try and apply a bit more pressure all over the pitch from start to finish, really.
"There is an obligation to try and stop the opposition, frustrate the opposition but also try and impose ourselves on them so they have to do a bit more work as well."
