Tottenham recently exercised an option to extend Son's contract by a year in January, preventing him from leaving the team for free this summer. However, the club is now open to selling him, knowing that there is significant interest from the Saudi Pro League.
Several top clubs in the Saudi Pro League have expressed interest in signing Son, who is considered one of the best players in the world. Tottenham is willing to cash in on this interest and sell Son to the highest bidder.
