As Heung-min Son edges closer to an exit after ten years at Tottenham Hotspur, it has now emerged that the Lilywhites may be in line to receive a huge financial blow.LAFC FC have now submitted an offer for Heung-min Son, with the Californian side determined to bring the 33-year-old through the door this summer.It remains to be seen whether their offer will be accepted, but Son will be part of Tottenham’s pre-season tour to South Korea, with his presence being crucial for the Lilywhites for commercial reasons.Some outlets have claimed that Son is now ‘increasingly likely’ to join LAFC this summer, and a new update has now suggested that the 33-year-old’s exit may make a big dent on Tottenham’s balance sheet.(Credit @thefrederikkejensen / Instagram)Tottenham’s revenue will take a massive hit when Heung-min Son departsThe Daily Mail have pointed out that an estimated 5,000 Koreans attend Spurs home games on average to catch a glimpse of their idol.Many of them spend big in Tottenham Hotspur’s megastore while millions of fans back in South Korea also digitally engage with the club’s content.The outlet says that industry experts estimate that Son-related income is worth a whopping £40m-£60m to Tottenham annually, with the club set to lose much of it when the forward departs.The decision to sell the 33-year-old could thus end up being costly for Tottenham in more ways than one, with reports indicating that Spurs are willing to accept a cut-price fee for Son.Daniel Levy has tried to future-proof the club’s financesIt is fair to assume that a percentage of the Korean fans will continue supporting Tottenham after Son’s departure, but many may see their enthusiasm drop after their countryman’s exit.That is perhaps part of the reason why Spurs have signed Yang Min-Hyeok, who many hope will become the next big Korean football star.However, the 19-year-old may not be ready to make the jump to the Premier League just yet, with reports indicating that Yang is likely to be loaned out by Tottenham again this summer.READ MORE: Mathys Tel reveals his Thomas Frank homework after permanent Tottenham switchThe post How much income Tottenham could lose once Heung-min Son leaves N17 appeared first on Spurs Web.
