Football finance expert Stefan Borson is of the opinion that Daniel Levy will sanction a summer sale for half the asking price that has been mooted in the press over recent weeks.
According to reports, Thomas Frank has given the green light for Tottenham to cash in on Son, who has just a year left in his contract in North London.
It has been alleged the Tottenham boss is happy for the South Korean to stay at Spurs, but only if he accepts that a bit-part role during the upcoming season.
The confirmation of that came when Frank failed to mention Son among the players he is looking forward to working with, instead naming Dominic Solanke, Rodrigo Bentancur and James Maddison as the senior Tottenham stars he is excited to manage.
How much will Tottenham demand for Heung-min Son?
It was reported last week by Football Asian that, amidst interest from Saudi Pro League clubs, Spurs will demand £50m for Son’s services, which reflects his value to the club both on and off the pitch.
A few days ago, journalist Ben Jacobs suggested that Saudi clubs are willing to offer €40m (£34m) for the Tottenham captain, with Al Ahli, Al Nassr and Al Qadsiah thought to be at the front of the queue to land the forward.
Stefan Borson has now said that an offer of £25m would be enough to convince Levy to sell the Asian superstar since the Lilywhites will be keen to take his salary off their wage bill.

When asked how much Tottenham will demand for Son, Borson told Football Insider: “Clearly, he is a big cost. He’s probably the biggest earner. It’s a case of really how much contribution is he going to make next season? His contribution has been waning over the last couple of seasons.
“You would think that if they could get £25 million out of Saudi, then that would make a lot of sense for Spurs. It’s the sort of deal that you would think Daniel Levy would want to do, and it would make a lot of sense for Son as well because the sort of money that he would get with the tax break would be very attractive.
“I think Spurs will just have to deal with the loss of the South Korean impact. I think they did sign a South Korean youngster last summer, just presumably to try and maintain some continuity with that attractiveness to the South Korean market.
“But I think it’s going to be the wrong way around if you’re paying Son just to stay, effectively to be a mascot for the South Korean market. I think that’s unlikely.
“From a footballing perspective, I think now could well be the time for him to leave. But probably it’s one of these where only Saudi could do that deal given his wages. The question is always with Saudi interest, is that something that the player would even contemplate?”
Why all signs point to a Spurs exit for Son this summer
The worrying thing for Tottenham Hotspur fans is that there have been no reports of the club considering entering into contract talks with the 32-year-old.
If Spurs were planning on hanging onto the forward, one would have expected them to initiate exploratory talks with his representatives already.
