Of all the World Group play-offs to take place next weekend, the tie between Netherlands and Austria is one of the closest to call.
Dutch No. 1 Robin Haase thinks the clash on 13-15 September with European rivals Austria will be "interesting" because he believes it is a "50-50" contest.
The world No. 59 from The Hague has pinpointed one of the keys to the outcome of the tie as being the battle of the No. 1s between himself and Jurgen Melzer.
"It's tough to play someone like Melzer," said the 26-year-old who has lost all of his previous encounters against the Austrian Davis Cup stalwart. "Davis Cup is a different situation because you play not as an individual but you play as a team and I think it’s something special for the players."
What would make the occasion even more memorable would be a return to the top flight for the Netherlands after they were defeated by a Roger Federer-led Switzerland this time last year.
Haase added: "It’s also important because it’s that big so it’s good for the country to be in the World Group, so we would be really excited to win."
Standing in the Dutch team's way is not only Melzer but the up-and-coming Andreas Haider-Maurer and a well-established doubles duo of Alexander Peya and Julian Knowle.
But Haase is hoping the rest of his team, which includes a good balance of singles and doubles know how in Jesse Huta Galung, Thiemo de Bakker and Jean-Julien Rojer will help lift his own level to be sufficient to move back into the top flight for the first time since 2009.
"You’re still alone on the court," explained Hasse. "Normally you don’t want to lose for yourself but now you don’t want to lose because you don’t want to disappoint the teammates and the crowd, so it gives you something extra."
Netherlands plays Austria in the World Group play-offs on 13-15 September in Groningen. Play starts at 1pm local time (11am GMT) on Friday 13 September.
