Murray repeats GB quit threat
Andy Murray has reiterated his Davis Cup quit threat, insisting improving his ranking and winning tournaments must come first.
The 20-year-old British number one believes representing Great Britain may hinder his career.
"I don't know exactly how long I will continue playing Davis Cup," Murray said in the Guardian. "I'm not going to just say I'm going to retire from it when I'm 21."
The world number 11 is concerned that the higher he gets in the rankings, the longer he will remain in tournaments and the tougher his schedule will become.
Although he will play for Great Britain in next month's Davis Cup tie in Argentina, Murray would not be keen to be involved in too many more away ties.
He said: "The Argentina match is a tough tie, but I'm doing my best to make sure that I can schedule my tournaments around it so that I can play.
"If there (were) a home tie straight after (the Australian Open) it (wouldn't) make sense for me to miss the tie.
"It's a pretty easy option just to play in Britain but, when it's an away tie, the last thing I want to be is on the tour and travelling here and there all over the place."
