Australia’s captain Lleyton Hewitt has revealed that he “couldn’t be happier” with how his team is shaping up ahead of this week’s Davis Cup by BNP Paribas World Group quarterfinal tie against the United States.

Speaking at the official media conference on Tuesday morning, Hewitt claimed that the quality quartet of Nick Kyrgios, Jordan Thompson, Sam Groth and John Peers were fit and raring to go at Brisbane’s Queensland Tennis Centre.

“Everything’s been going according to plan so far,” he said. “I couldn’t be happier with how the boys are gelling together – Nick obviously arrives in here terrific form and the other boys have hardly put a foot wrong since we got here.

“The boys have become a really close unit, there’s great chemistry amongst them and with the wider group of support staff. It’s not just this week that the guys all support each other, it’s all year round so I couldn’t be prouder of the commitment they’ve shown to playing the Davis Cup for Australia.”

For his part, Kyrgios believes he is playing some of the best tennis of his career, having reached his third semifinal of the season in Miami last week.

Kyrgios arrived in Brisbane on Monday morning following his titanic tussle with eventual champion Roger Federer in Miami, and the Canberra native is confident of extending his rich vein of form on home soil.

“My level’s always been pretty good, but I think mentally I’ve really stepped it up in recent weeks,” he said. “I’m competing for every point, and I haven’t always had that mindset in the past.

“I was pretty tired when I got here, but being around these boys again has lifted me. The last Davis Cup tie really helped me. I’ve been in a good headspace since then, it’s great to know that the boys are all supporting me. We message one another pretty much every day, so it’s a fun environment to be in and I’m really enjoying it.”
