The LTA have withdrawn their funding for Bogdanovic

Alex Bogdanovic has been given three months to convince the Lawn Tennis Association to back him again.

The 19-year-old has been left to go it alone by the LTA because of a perceived lack of commitment.

The Serbian-born left-hander will meet Mark Petchey, head of men's performance at the LTA, after Wimbledon to review the situation.

Petchey told BBC Sport: "Ultimately, it is Alex's career and he has got to take responsibility for himself."

He added: "There are two ways for him to go. He can either be totally frustrated and not apply himself or recognise he hasn't stepped up to the plate and double his effort."

The LTA had been providing Bogdanovic with �80,000-a-year funding, the services of Swedish coach Martin Bohn and free use of Queen's Club in west London.

This has all been withdrawn, although Bogdanovic has been given free access to a sports psychologist.

And, contrary to some reports, he will not be denied a wildcard for Wimbledon, as this is a matter for the All England Club to decide before the tournament.

This isn't something that's happened overnight - we have tried very hard with Alex Mark Petchey

Bogdanovic's attitude has been a concern for Petchey, LTA performance director David Felgate and Davis Cup captain Jeremy Bates for some months.

And matters came to a head when the left-hander refused to play in a Futures tournament in Athens that started on 22 March.

He argued he was still suffering from the food poisoning that had forced him out of a Challenger event the week before in Sarajevo.

Petchey insisted Bogdanovic should travel and see if he was fit to compete when he got there.

The teenager refused and was expelled from the LTA men's squad.

"The top players have huge desire and commitment - it is not just about forehands and backhands," Petchey said.

"Only the toughest survive. Pete Sampras played while throwing up at the US Open a few years ago and won his 14th Grand Slam there last year despite having shin splints and being unable to train.

"This isn't something that's happened overnight. We have tried very hard with Alex and six months ago I laid things on the line for him, but he didn't improve."

The LTA are delighted with Andrew Murray's progress

However, Bogdanovic argued he had been unable to travel to Athens and was harshly treated by the LTA.

"I was so ill there was no way I could travel. I had a fever and was shaking," he told BBC Sport.

He did play the following week, in Syros in Greece, and reached the semis before losing to Pavel Snobel of the Czech Republic.

Bogdanovic was seen as the bright hope of British tennis only a year ago.

Last February he played in Britain's Davis Cup tie against Australia and took a set off Lleyton Hewitt before beating Todd Woodbridge.

The LTA's frustration with Bogdanovic is in marked contrast to their delight at the progress of 16-year-old Andrew Murray.

"We have no problems like that with Andrew whatsoever," Petchey said.

"He's in excellent condition and is mentally very switched on."
