Novak Djokovic told rowdy British fans to "shut up" after leading Serbia to a 2-0 victory in the Davis Cup quarter-finals in Malaga.

The world number one showed his annoyance with a section of the 5,000-strong British support by cupping his ear and blowing ironic kisses at the end of the first set of his 6-4 6-4 victory over Cameron Norrie.

When the same group of fans began drumming during Djokovic's on-court interview, the Serbian responded: "Learn how to respect players, learn how to behave yourself," before adding, "no, you shut up, you be quiet".

Earlier, Jack Draper fell to a 7-6 (2) 7-6 (6) defeat by Miomir Kecmanovic in a opening rubber that was a must-win.

On his spat with the supporters, Djokovic said: "In the Davis Cup, it's normal that sometimes fans step over the line but, in the heat of the moment, you react too, and you show that you don't allow this kind of behaviour.

"They can do whatever they want, but I'm going to respond to that. I was trying to talk and they were purposely starting to play the drums so that I don't talk and they were trying to annoy me the entire match. So we had a little bit of a chat in the end."

The tie did not get under way until 6.10pm Thursday, more than two hours later than billed, because of the over-running first match of the day between Italy and the Netherlands.

The near-capacity crowd, which also included a sizeable number of Serbian supporters, gave the event the sort of authentic Davis Cup feel that has so often been missing since the switch from the home-and-away format.

Among those sat in the stands at the Palacio de Deportes Martin Carpena was Dan Evans, who had hoped to build on his brilliant performances in Manchester before a calf injury prematurely ended his season.

But even the British number two would have had his work cut out against an inspired Kecmanovic, who was chosen ahead of the higher-ranked Laslo Djere and fully justified the decision.

Draper had the better form coming in having reached his first ATP Tour final this month and had beaten Kecmanovic - ranked five places higher at 55 - earlier this year, but the Serbian was dominant on serve and edged two tie-breaks.

Djokovic had lost only six of his 61 previous matches this season, with just one defeat since the Wimbledon final, while his Davis Cup record is utterly formidable.

It is 12 years since he lost a singles match in the competition, and even that was by retirement, with now 21 straight wins and only four sets dropped.

Norrie had managed only a single set in three previous meetings and has endured a miserable run since the clay-court swing back in the spring, but he was captain Leon Smith's only option once Andy Murray pulled out with a minor shoulder injury.

He did not put in a bad performance by any means, but was fire-fighting from the moment he was broken at 2-2 in the opening set and won only eight points on Djokovic's serve during the contest.

On Friday, Australia ended the surprise run of Finland to reach the final for the second year in a row.

Finland defeated Croatia and the USA in the group stage in September to qualify for the quarter-finals for the first time and then upset defending champions Canada on Tuesday.

Backed by thousands of fans in Malaga thanks to a sizeable local population of ex-pats, they hoped to continue the fairytale but found Australia too strong.

Otto Virtanen, ranked 171, had been the unlikely star of their run but he was beaten 7-6 (5) 6-2 by Alexei Popyrin, a late call-up to the Australia team and picked ahead of Jordan Thompson, in the opening match.

The Finns were boosted by the return of their number one Emil Ruusuvuori from a shoulder injury but he was unable to capitalise on a good start against world number 12 Alex De Minaur and went down 6-4 6-3.

Australia will now try to go one better than last year’s 2-0 loss to Canada when they take on either Serbia or Italy in the final.

It is a 49th Davis Cup final for Australia but they have not lifted the trophy since 2003.
