Birmingham Ladies are confident of upsetting the odds this weekend and securing victory in the biggest game in their 46-year history.
They travel to Sweden for the second leg of their Champions League semi-final against Tyreso on Sunday, having drawn the first game 0-0.
If they are to prevail they will have to subdue five-times world player of the year Marta and skipper Karen Carney is confident they can handle her threat.
"Marta didn't get a sniff in the first leg," Birmingham's most experienced player told Sky Sports News. "She's won everything individually and collectively, she's a fantastic player and you can't take that way from her.
"She's a great ambassador for the game as well but hopefully she's very quiet on Sunday.
"It is exciting, there is nothing to worry about because we are the underdogs, we have got nothing to fear. That's what we have got to believe. We are playing a team stacked full of international calibre and we have just got to out and play our own game."
Arsenal Ladies are the only English team to have been crowned European champions and Birmingham Ladies beat them home and away in the quarter-final.
But manager David Parker acknowledges that there is huge gulf in resources between the Swedes and his own side.
"Tyreso are the galacticos, they are the Real Madrid of women's football," he said. "Everyone knows that they have gone bankrupt, that they have splashed a lot of cash. To give you an idea, Marta in on more wages a year than we have to operate the whole club."
