Yuki is the highest-ranked Indian player at number 179 while Jose Statham is Kiwi's best ranked player at 317.
"The question is not what ranking you have but the test is in winning the tournament," Yuki said after arriving here along with Divij Sharan.
"We have the firepower and if we stay focused, we can win the tournament."
Yuki also said that he was not under pressure though he was leading the Indian charge in the absence of big players.
"The Davis Cup presents a good opportunity for the team as we will be playing in front of a home crowd and this will be a great advantage."
India are playing without Leander Paes and Mahesh Bhupahti, the country's best doubles players, but Yuki felt gradually the young players will do well.
"It is very difficult to replace the Leander-Bhupathi combination, but the future of Indian tennis looks bright as many young players are coming up," he said.
Yuki and Divij underwent practice along with other teammates, who had arrived here early.
