SPORTS management giant TLA Worldwide has sold its US businesses and is making "positive progress" in doing the same with its Australian arm.

TLA's Australian business looks after about one-third of all AFL footballers and has a near monopoly on the coaching market, as well as boasting high-powered clients in sports such as cricket, swimming and netball.

Among TLA's top AFL clientele are Jarryd Roughead, Trent Cotchin, Bryce Gibbs and Ben Brown, plus coaches Nathan Buckley, Adam Simpson and the Scott twins, Chris and Brad.

The company released the following statement overnight: "(TLA Worldwide) is making positive progress regarding the sale of its Australian businesses (comprising the Australian sports marketing business) and discussions are continuing.

"If such a sale of the Australian businesses, which would also require shareholder approval, were to proceed, and the sale completes, then the company would become a 'cash shell' … but further information on this will be provided as and when applicable."

Collingwood premiership player Craig Kelly founded Elite Sports Properties in 1996, with TLA purchasing ESP for up to $25.5 million in 2015 and Kelly remains chief executive.

The athlete management and sports marketing company's client base in Australia rocketed from 250 to more than 700 at the time of that deal.

TLA Australia is also involved in the restructure and rebranding of Victoria's elite under-18 competition, the TAC Cup.

AFL.com.au confirmed in August plans for the Brisbane Lions, Gold Coast, Northern Territory, Sydney, Greater Western Sydney and Tassie Mariners to enter teams in the competition.

It is unclear at this stage what the potential sale will mean for the Australian business.
