Andy Murray has confirmed that his return to the Team GB Davis Cup for this weekend's tie with Luxembourg at Braehead could be permanent.

The world No.4 has not played in the tournament since he won both his singles rubbers in a 3-2 loss to Poland in 2009.

But now after being paired with Luxembourg No.2 Laurent Bram and playing under the captaincy of his childhood coach Leon Smith for the first time, Murray says he is back in love with Team GB after following the ill-starred captaincy of John Lloyd.

The three-times Wimbledon semi-finalist said: "I will play more, of that there is no doubt. A few things happened in the past that I was maybe not happy with and didn't enjoy in the last few ties but I'm looking forward to it again.

"So for me personally it has been great to be back in Glasgow this week and great to be back around the guys and I will definitely play more in the future."

Without doubt Murray's return to the team is vital to our hopes. Had he not played then Luxembourg's Gilles Muller, who at 81 is the next highest-ranked player in the tie, would have been a firm favourite to win both singles.

Muller made the third round at Wimbledon and has a decent hard-court pedigree having made the US Open quarter-finals.

Today's tie will be opened by GB No.2 James Ward facing Muller, and Murray admitted that it will be vital for Ward to make the most of his recent good run at Queen's Club.

The Englishman made the semi-finals before losing out to Jo-Wilfried Tsonga in his best-ever performance on the ATP World Tour.

Murray said: "This Davis Cup team is not far away from being an excellent one. If James can push on from his run at Queen's Club and get to play guys like Gilles Muller on a regular basis on the tour and start beating them then it is going to be a big plus for the Davis Cup team.

"We already have three or four guys in the doubles who are closing in on the top 50 and I play well in the singles so, hopefully, James and Dan Evans can push up the rankings too."

Murray's fellow-Scot Colin Fleming has withdrawn with a foot injury and was replaced by Evans, who is essentially cover for Ward in the second singles berth.

But with Murray being partnered by his brother Jamie in tomorrow's doubles tie against Mike Vermeer and Laurent Bram, the elder Murray brother says he is relishing the chance to star in front of a sold out Braehead Arena.

Jamie Murray said: "It is great to be back in the Davis Cup side again. I missed the last year because my form was good enough but now it is fantastic to be back in the side and playing with Andy in front of a Scottish crowd."

Skipper Smith has backed the Murray brothers to claim victory in the doubles tie which could prove pivotal to Team GB hopes.

He said: "The doubles team was always going to be Andy and Jamie. Andy is our best singles player and Jamie is our No.1 doubles player so they are our strongest pairing.

"The doubles tie is an important rubber in the whole match and we have to put our strongest pairing. For Andy and Jamie to be playing together in front of a sellout Scottish crowd at Braehead will definitely get the best out of them."
