Son has been a key player for Tottenham since joining the club, but struggled with his form after being hit with injury last season.
Tottenham play against Arsenal on July 31st in Hong Kong and then face Newcastle in Seoul three days later. From a commercial standpoint, Son's presence in these matches is crucial for Spurs.
Tottenham set for life without Son
According to reports from Sportal, Tottenham are highly likely to sell Heung-Min Son to Saudi Arabia this summer.
However, the London club will wait until their preseason tour of Asia concludes before making a final decision.
This is because if Son departs beforehand, the club will face issues with the tour organisers, as local fans are anticipating seeing the Korean star.
New Tottenham manager Ange Postecoglou is planning to bring in new wingers, with Bryan Mbeumo and Antoine Semenyo among his targets. Mathys Tel has already been signed.
Son is a true Tottenham legend, having played 372 matches and scored 145 goals for the club since joining in 2015.
