ANDY MURRAY knows reacquainting himself with some old friends can be an emotional experience.

Back in 2011, the normally stoney-faced Scot was reduced to tears by the presence of a home crowd at Braehead Arena following his straight-sets win over Luxembourg's Gilles Muller.

It was one of the rare occasions Murray has the privilege of playing in front of a Scottish crowd with the 27-year-old spending most of the year touring the globe in the pursuit of his next Grand Slam.

It is an experience the Olympic champion will get to enjoy again today.

Murray is first up at the Emirates Arena as he takes on Donald Young in the first rubber of the Davis Cup tie between Great Britain and USA.

And he confessed to SportTimes it can be difficult keeping your emotions in check at such an occasion.

The world No.5 said: "I think for me I would imagine the beginning of the matches are normally where I find it would affect me most in Davis Cup.

"At the beginning when you come out, the national anthem, the crowd get right into it at the beginning.

"Yes, it's an emotional experience. And sometimes at the beginning of the matches you can be a bit fired up, or amped up, whatever you want to call it.

"But that tends to subside, I would say, after the first 15 or 20 minutes.

"Than you just get down to trying to concentrate on the tactics, the process and trying to win the match."

During yesterday's draw, nerves did not seem to be getting to Murray as he sat and joked with his team-mates and the assembled press pack.

He was first name out of the hat and as a result will open up proceedings at 1pm today against world No.45 Young.

It is an early duty against the left-handed 25-year-old that Murray seems unmoved over.

He said: "I don't mind. It's not like it's going to be too late.

"If the matches start at 7pm you prefer to get on first because it can affect your sleeping patterns and stuff the next day and your recovery.

"But from 1pm or 4pm it doesn't make any difference."

After Murray's first match today, he is next due to be in action on Sunday when he faces world No.20 John Isner.

His brother Jamie and Dominic Inglot have been selected to play in Saturday's doubles match against the Bryan brother of Bob and Mike.

The news that Murray has not been selected to play with his brother will be a blow to many of the fans wanting to see the siblings pair up.

However, captain Leon Smith has until mid-day on Saturday to change his line-up, and two-time Grand Slam champion Murray is comfortable with being called upon if needed.

He said: "We obviously played a bunch when we were younger together.

"We haven't played so much recently, but obviously it's an advantage I know his game well he knows mine well.

"I would say it's unlikely I would play the doubles on Saturday, if its required then it would be nice to play with Jamie or Dom - or Wardy [James Ward].

"They've both started the year very well, they're both here by right, Dom has had some big wins over the Bryans this year, and Jamie's consistency over the past seven months has been very good.

"So whichever team we put out will have an opportunity of winning the match providing they play great tennis."
