The nations are doing battle for a place in the World Cup and Evans' recent run to the third round of the US Open has increased confidence in the team's chances.
The 23-year-old defeated 11th seed Kei Nishikori and world number 52 Bernard Tomic before succumbing to 19th seed Tommy Robredo in four sets.
Former Great Britain Fed Cup star Croft, who is presenting Eurosport's coverage of the tie, is full of praise for Evans and thinks his future looks very bright.
"What's happened with Dan Evans in the last few weeks has been absolutely amazing," she told sportinglife.com.
"It's such an inspiration and he's a real character like the Artful Dodger.
"He's so amusing but it's taken him a bit of time to mature and suddenly the penny has dropped.
"If he can continue in a really positive vein then it really does make it exciting for the future. To beat Nishikori and Tomic proves he can mix it with the best."
The clash against Croatia will be played on clay and Croft thinks Andy Murray's quarter-final exit at the US Open won't be a problem the Wimbledon champion.
Murray lost 6-4 6-3 6-2 to Swiss ace Stanislas Wawrinka at Flushing Meadows but the extra preparation time for this tie could prove to be a good thing.
"It's an advantage in that he will have a bit more time to prepare on the clay," Croft added.
"It's going to be a real test of his character to pick himself up after such a difficult defeat against Wawrinka.
"Andy's admitted in the past that he's been flat after defeats in Grand Slams so it could be a positive thing that he's coming out and representing his country."
