World number three Andy Murray thinks that the current funding system in Britain should stop at 18 years of age, to allow players to fend for themselves.
The 24-year-old is the only British player ranked in the top 100 tennis pros in the world, and believes that the funding system is at fault.
"Do you know that in Spain, at 18, your funding stops?" the Daily Mail quotes Murray as saying. "From there, you get nothing that you cannot earn for yourself.
"We're funding guys to 27, 28 - while in the most successful tennis nation in the world you're basically on your own. Maybe there's something in that."
The Scot thinks that the training of British coaches needs to be altered so more talent can come through the ranks.
"When I went to Spain, from the best players to the worst players we were all taught the same way, all given the same drills," he added. "They had a structure and they stuck to it.
"Go to our national centre and you've got 10 different nationalities all coaching a different way. If we don't get the results straight away, we panic and change direction.
"There is no confidence in our technique, no sense of sticking to an idea, no identity, no consistency in the way we teach tennis, so naturally there is no British style."
Murray will compete in the ATP World Tour Finals in London from Sunday.
