A "very emotional" Perth Glory owner Tony Sage says he is close to finalising a deal to sell the majority of his stake in the A-League club to a London-based cryptocurrency group, but has assured fans the club's name, colours and "heritage" will be retained.

Key points: A new group, the London Football Exchange, is set to buy Perth Glory

A new group, the London Football Exchange, is set to buy Perth Glory Tony Sage says he waited for the right deal to protect Glory's heritage

Tony Sage says he waited for the right deal to protect Glory's heritage He is hoping to reach a deal within 48 hours to sell 80 per cent of the club

The millionaire businessman has been the sole owner of the Glory since 2009.

But Mr Sage said he was no longer able to compete with the financial power of other A-League clubs and had been looking for an investment partner for the past 18 months.

"Last year's loss was about $2.9 million, which is a huge loss to take on by myself," he said.

"I'm the only sole owner left in the league."

Mr Sage said he had received four offers for the club over the past 18 months, but each of them came with conditions he could not accept, including changing the club's name or colours.

"One thing I am very big on is the history of Perth Glory, so I've been patient," he said.

Mr Sage said he had been negotiating for about four weeks with a new cryptocurrency group, the London Football Exchange, which was looking to buy several football clubs around the world.

He was currently in Dubai, on his way to London, where he hoped to finalise a deal within 48 hours to sell 80 per cent of his stake to the group.

Deal will bring 'many opportunities': Sage

Mr Sage said he would retain the remaining 20 per cent stake and would also become chairman of the London Football Exchange from March 1.

"It's not quite a done deal yet. They wanted 100 per cent of the club, I was unwilling to go to 100 per cent," he said.

"I wanted to retain [a share] because I think the future of Australian football is going to be huge."

Mr Sage said he was "very emotional" when he told Glory players and staff of his plans at a meeting at the club yesterday.

"I said actually it was a sad day for me, but it's an exciting future for the club," he said.

"We'll be part of a group that has six or seven clubs in it over the next two years.

"From about next season, the owners will own the [A-League] and that's a massive change in itself. The FFA won't be involved.

"We're going to be set now with a big partner … so many opportunities will arise from this transaction if it happens in the next 48 hours."

Mr Sage said he expected Perth Glory would continue to post losses for another two years until a new TV rights deal was negotiated.

What is the London Football Exchange?

According to its website, the London Football Exchange is the world's first football club stock exchange that will allow fans, traders and investors to acquire shares.

But if Glory supporters are offered the opportunity to buy into the club in the form of cryptocurrency it should be done with caution according to Leigh Travers, executive director of blockchain firm Digital X.

"I think fans that are looking to buy a LFE token to get ownership need to do a bit of research first to make sure what they are buying is exactly what they are going to get," he said.

"Understand exactly what it is you are buying, whether it is the ability just to use it as a currency to go purchase merchandise or something like that or if it is actual ownership," he said.

Mr Travers said a football club like the Glory would be an attractive proposition for the London Football Exchange as it looked to expand overseas.

"I think that Perth Glory has a strong supporter base, it has had a very successful history and it is a big jurisdiction jump from London to Australia," he said.

"I think that might be a springboard for some other activities they are looking to do — try things out in a more concentrated local market see what the demand is and then bring it to other market places as well."
