"I rate our chances 40-60 in favour of the U.S. but you never know. There are so many variables that could have a bearing on the final outcome."

Davydenko, the highest-ranked player in this year's final, agrees Russia face an uphill task.

"It's pretty tough because we play in America where we know we have less chance of victory," he said. "If we win, it will definitely be the best moment of the year for me."

The United States, winners of a record 31 Davis Cup titles, are desperate to taste success for the first time in 12 years.

"This has been such a big goal for us as a team," inspirational captain Patrick McEnroe said. "Yes, there is pressure but, at the same time, pressure is a privilege."

World number six Roddick, whose straight-sets victory over Jonas Bjorkman set up a 4-1 victory for the U.S. over Sweden in their Davis Cup semi-final, is in upbeat mood.

"We're feeling confident but getting that confidence to translate to the court and getting a win is a tall task, especially when we lost to them last year," the big-serving American said.

"But I like our team. We have been dreaming for a while of having a home final and I think we're all just really excited about the opportunity. And we have the best doubles team in the world in our corner."

The dominant Bryan brothers, Bob and Mike, have lost just once in 13 doubles Davis Cup matches.

Blake, like Roddick, believes the Memorial Coliseum surface will give the U.S. a massive boost.
