British former world number one Andy Murray "just needs the chance to compete" as he continues to struggle with injury, says his brother Jamie.
The 34-year-old three-time Grand Slam champion has been plagued by a groin problem but is determined to play in this summer's Wimbledon.
Older brother Jamie, 35, believes Andy could still be a threat at the tournament if he can get himself fit.
"It has been frustrating for him," Murray told BBC Scotland.
"Obviously he keeps getting niggles and stuff that has set him back, for him he just needs to get a clear run of events, and that is what has been difficult for him for various reasons over the last few months."
Andy Murray competed in the Italian Open earlier this month and is set to begin his grass-court season next month at the Nottingham Open.
Jamie Murray said: "His game is good, he just needs the chance to compete.
"Hopefully with the grass season coming up he can get a good four or five weeks of tournaments under his belt and try to build up some momentum for himself."
