ANDY MURRAY will shine brighter than ever before in 2015.

That is the view of Davis Cup captain Leon Smith as the Scot begins to prepare for an assault on more silverware in the new year.

Murray flew out to Miami earlier this week for his usual winter training camp to get himself in shape for the rigours of the new season after a gruelling 12 months.

It has been a disappointing year for the world No.6 who failed to win a Grand Slam while his defence of the Wimbledon title was halted in the quarter-finals by Grigor Dimitrov.

However, there was much disruption for Murray to contend with in the early part of 2014 as he recovered from back surgery last September while also dealing with the departure of coach and mentor Ivan Lendl in March.

But having recovered his form latterly to produce a string of astonishing results to make it the ATP Tour finals in London last month - despite not making it out of the group - Smith is confident Murray still has much more to give.

The Davis Cup captain will bring his fellow Scot to Glasgow in March for a World Group tie against the USA, and he believes that will be just one highlight for Murray as he tips the Olympic champion to reach new heights.

"I don't think he's far away," Smith told SportTimes. "He will recognise there are areas of his game he can improve to make sure he keeps increasing the likelihood of winning another Slam, but he's going to be there or there abouts.

"His form at the end of this year is strong and he's now focusing on adding that extra dimension to make sure he's competitive against the likes of Novak Djokovic.

"Next year is going to be a very good year for him. He's finished this season not how he would have liked it at the O2, but the six weeks previous was simply phenomenal.

"He's going to be very fit, very strong, and challenging for the Grand Slams in 2015. We're going to see the very best of Andy Murray."

Being at the peak of his powers for the first Grand Slam of 2015 - the Australian Open - is an obvious target for Murray.

To kick start the new Tour season in January he will need to banish any thought of how the previous one ended for him.

The British No.1 needed to beat Roger Federer in straight sets at the ATP Finals in London last month to have any chance of progressing to the next round.

Instead he was dispatched in a straight sets 6-0, 6-1 trouncing. The only saving grace for Murray was that it only lasted 56 minutes.

But it's an experience that Smith is sure his old friend will not dwell on for too long.

He said: "I've had a couple of texts from him here and there, but he's fine.

"I think Andy responded very well to come out and play in the final [Federer pulled out injured] and the exhibition. It shows he is in a determined mood and how much he cares about the British public.

"His 10 weeks in Miami is when he will work with his coaching team and really think about what key areas of his game he wants to address, as he always does, so he's back in Australia ready to challenge."
