Glasgow City admit they need to play out their skins and hope Paris Saint-Germain have an off day to avoid an exit from the Women's Champions League.
The Scottish champions go into Saturday's quarter-final second leg in France 2-0 behind.
And Glasgow head coach Eddie Wolecki Black said: "We'll need a lot of luck and they will have to play poorly, but there's always hope.
"We are certainly not going to go over to Paris for a holiday."
Wolecki Black admitted that Glasgow, who are in the quarter-finals for the first time, had gone into the first leg at Airdrieonians' Excelsior Stadium simply looking to keep the tie alive.
Unlike Bristol Academy, who were hammered 5-0 at home by Frankfurt in their first leg, the Scots go into their return game with hopes of progressing.
"It was obviously a difficult 90 minutes and we knew it was going to be like that," said Wolecki Black.
"PSG were huge favourites before the tie and they are more so now.
"But leads of 2-0 have been turned round before."
Glasgow, who have won eight successive domestic titles, are used to dominating possession and Wolecki Black admits that it had been difficult to "change behaviour" in a few weeks to a more defensive set-up for Europe.
However, he hopes that "now we know their players", they will be more able to cope with the challenge.
Glasgow captain Leanne Ross said: "It is a different mindset when you come and step up from our league to the Champions League.
"There's things we need to improve on, but Eddie will go away and have a good look at the game and will know exactly what we need to do leading up to the game next week.
"We are used to having quite a lot of possession in our league games, but we've got a lot of international players as well and we know what we need to do against quality opposition.
"Personally, I think we sat too deep. If we can maybe put pressure on them higher up the pitch and pressure them into mistakes, we can maybe sneak a goal and get back into the tie."
Midfielder Ross, capped 105 times for Scotland, praised goalkeeper Lee Alexander.
"Lee's been fantastic in the whole competition," added the 33-year-old. "She suffered a real bad injury in the last round, so she's done really well in her rehab and she's come back in and has certainly kept us in the tie with one of her saves."
