Both Davis Cup semi-finals level after opening day of singles

France's Lucas Pouille and Jo Wilfried Tsonga take part in a press conference in Lille northern France

"I can't relate to anything (Tomic) says anymore", said Kyrgios, who met Steve Darcis in the second singles match yesterday. "I knew it was going to be tough, especially on this very slow clay court".

Australia captain Lleyton Hewitt hailed the fighting spirit of Nick Kyrgios after the enigmatic star's Davis Cup victory over Steve Darcis in Brussels. "Rusty (Hewitt) has helped me a lot".

As a result playing captain and doubles ace Nenad Zimonjic has chosen Dusan Lajovic plus first-time nominee Laslo Djere and Filip Krajinovic in an upset bid.

"It's once every blue moon you get in the semi-finals of the Davis Cup and we have a real chance to win it", Kyrgios said.

Kyrgios stormed imperiously through the opening set, sending down eight aces without losing a point in five service games.

Kyrgios appears to be over the shoulder injury which short-circuited his US Open campaign, and a 3-0 head-to-head record against Belgian no.1 Goffin augurs well for the Aussie no.1.

Having taken the first set, Kyrgios was broken at the start of the second and although he saved three set points in game nine, the Australian netted a forehand, allowing Darcis to level.

However, the world No.20 silenced the crowd in emphatic fashion by taking the fourth set 6-1 as Darcis struggled to counter his huge serve, with Kyrgios saving a break point with 227kph ace.

It allowed Kyrigios to see out the match to seal one of his best victories in an Australian shirt. But 18-year-old Denis Shapolavov prevailed 7-6 (7/2), 6-4, 6-7 (6/8), 4-6, 6-1 over Yuki Bhambri to level the tie.

Neither of the Belgians play a great deal of doubles but with Peers' regular Davis Cup partner Sam Groth not in the team, the Aussies will field a new-look doubles team.

Noah's team are favoured to progress to the final against a Serbian side sorely missing injured former world No.1 and 12-time Grand Slam victor Novak Djokovic, Viktor Troicki and Janko Tipsarevic.

Australia took a 2-1 lead against Belgium on Saturday after easily winning their Davis Cup semi-final doubles in three sets. World No. 80 Lajovic edged Lucas Pouille, ranked 58 places higher, 6-1, 3-6, 7-6 (9/7), 7-6 (7/5) in the first rubber of the tie also being played on clay.

Lajovic had cramps in his right foot towards the end of the fourth set and needed some help from Serbia player and captain Nenad Zimonjic to put his shoe back on after hitting an overhead victor for a 5-4 lead in the fourth-set tiebreaker.

Playing with the French Davis Cup team for the first time this season, Tsonga made a successful return in the team competition and won 7-6 (2), 6-3, 6-3.
