Manager Martin O'Neill expects Celtic to come under severe pressure in their Champions League play-off second leg - but stressed they will not simply try to protect their advantage.
They lead Austrian champions LASK 3-0 from the first leg and arrive in Linz on the cusp of a return to the league stage.
O'Neill cautioned straight after that impressive victory that the tie was not over, given LASK created a series of chances and had two goals chalked off for offside.
"They will get opportunities to attack and they are a formidable team, there's no question about it," said the Celtic boss, who hopes to have defender Austin Trusty available after a stomach upset caused him to miss training on Monday.
"I expect to be put under pressure quite a lot, but we just can't sit in there, and that's not our intention at all.
"I feel as if we're capable of scoring a goal in the game, and that's at least grounds for optimism. It'll be a tough old night for us, but we're capable.
"We want to try and get through. We'll throw absolutely everything at it to do so.
"I think that if we could qualify, it would give us a massive lift in every aspect."
