Chelsea boss Sonia Bompastor has warned of the threat posed by "underdogs" Austria Vienna in their Women's Champions League tie.
Wednesday's game is a meeting between experienced Champions League side Chelsea and the Austrians, who are competing in the league phase for the first time after securing their spot through the qualifying rounds.
Bompastor praised the strength of the visitors, adding that they enter the match with "nothing to lose."
"They were able to finish first in their league, St Polten has been the historical champion," she said.
"They were also able to eliminate Brann, who was a really good team in this Champions League. We need to be prepared to face a strong team in terms of the physical aspects but also a team who is ready in terms of the tactical aspects.

"The game plan is ready. We have a lot of respect for them because again, every game will be difficult.
"We know they are coming with no pressure, they are the underdogs. They have nothing to lose and that's important for us to be ready.
"I think we have quality enough to be able to have a good performance and to win the game, so we are going into the game confident, but not too confident - just the right level."
Bompastor revealed that Lauren James will be absent for the game but could return for their Women's Super League clash with Arsenal at the weekend.
The Blues boss added: "She picked up a small knock in training last Friday. She should be available for the game at the weekend but we don't want to take any risks for the game tomorrow."
Wednesday's other fixtures see defending champions Barcelona host Paris FC and eight-time winners Lyon travel to Servette Chenois, while OH Leuven face Roma.
