Andy Murray is not convinced Great Britain's first Davis Cup victory in 79 years will help boost participation in the sport.
The world No 2 won all three rubbers he was involved in as Britain defeated Belgium 3-1 in Ghent over the weekend.
But despite being part of a successful team campaign, Murray fears the success will not have a positive impact on grassroots tennis in Britain.
Speaking to a number of national newspapers, Murray said: "It's almost sometimes like I feel like you waste time because nothing ever gets done.
"I also don't want to waste my time talking about stuff. That's also the reality.
"I'd rather concentrate on my own stuff and when I've finished playing, I'll have a lot more time to try and help or give back to the game.
"But just now, I've got to concentrate on trying to win as much as possible.
"I don't know where the next generation are. I feel like I am saying 'I don't know' a lot but I genuinely don't know."
The Lawn Tennis Association (LTA) was heavily criticised by figures inside and outside the game for the failure to capitalise on Murray's Wimbledon success in 2013.
Participation fell in the months following his victory over Novak Djokovic and the LTA was faced with losing part of its funding from Sport England.
The latest figures were more positive and, despite Murray's pessimism, LTA chief executive Michael Downey said he was confident the Davis Cup triumph could lead to a growth in the game.
"These are very special, emotional moments that can actually drive interest in our sport, there's no doubt about it," he said.
"We need to keep in mind the time of year we have got. Participation peaks when you head into the spring/summer period.
"We've probably got a couple of great weeks of coverage (now). That is going to encourage participation."
