Captain Anne Keothavong says Great Britain cannot underestimate Sweden in the Billie Jean King Cup play-offs despite being the heavy favourites.
Britain are absent from the ongoing Finals in Seville following their 3-1 loss to France in April's qualifiers.
They will face Sweden at London's Copper Box Arena in a best-of-five series across Saturday and Sunday.
The winner will progress to next year's qualifiers, while the loser will drop into lower tier regional events.
"I feel like it's the first time in a long time we go into this tie as favourites, but this competition can mess with people's heads and people deal with pressure in different ways, " Keothavong told BBC Sport.
