During the tour, Son will be making a crucial decision about his future in the football world. His absence from the tour may cause complications with the organizers, which could be a concern for the club's massive fan base in Asia. Many fans are expected to attend the matches to see Son perform, and his decision will likely have a significant impact on the club.

At 32 years old, Son is one of the most experienced and iconic players in Tottenham's history. If he decides to leave the club, it would be a significant loss, and the team would face a difficult task in replacing him. Son has scored 173 goals in 454 appearances for Tottenham, and his departure would mark the end of an era for the club.

The club's fans in Asia are also heavily invested in Son's success, and his departure could have a significant impact on the club's reputation and financial backing. Son's popularity in Asia is well-deserved, especially after he helped the team win the Europa League trophy last season.

Tottenham has scheduled two friendly matches against Premier League rivals Arsenal in Hong Kong, followed by a match against Newcastle United in Seoul. This will be a crucial period for the club, as they try to balance their preparations for the upcoming season with Son's decision about his future.

Thomas Frank, the new manager of Tottenham, is already facing challenges in replacing players like Cristian Romero and Ben Davies, while also bringing in new talent like Byran Mbeumo and Mathys Tel. Replacing a player of Son's caliber would be a significant challenge, and the club will have to work hard to find a suitable replacement.
