Barbora Strycova lauded the Prague crowd following the Czech Republic's thrilling Fed Cup triumph over Russia.
The hosts claimed the title for the fourth time in five years with a 3-2 win as Strycova and Karolina Pliskova won the decisive doubles match 4-6 6-3 6-2 against Anastasia Pavlyuchenkova and Elena Vesnina.
It was a remarkable atmosphere inside the Czech capital's O2 arena and Strycova felt the home support proved vital.
She said: "We are feeling unbelievable, we can't describe it. I'm speechless because this atmosphere playing at home in front of such a crowd is unbelievable.
"I was believing that we could still do it [after going a set down] and believing in our game which we proved and then we did it at the end.
"This crowd was like a fifth person in our team. We really enjoyed it and I would like to thank to them. They pushed us forward."
Pliskova added: "I really enjoyed the whole week with the girls and even now this match was just an unbelievable feeling to play here in Prague and I'm just really happy that we have the trophy again."
