Son Heung-min is already 33 years old and he realizes that he is no longer young and it is difficult to compete at the highest level, if you look at his age maybe Son Heung-min can only play 2 or 3 more seasons to keep pushing himself at the top of his performance and now Son Heung-min has decided not to force it and prefers to enjoy the rest of his career not to play at the top level anymore, I think it's not a bad decision and the most impressive thing for me is the peak of everything, namely when last season Son Heung-min was able to present a trophy for Tottenham last season after 10 seasons with the Tottenham team.
With high dedication and loyalty, Son Heung-min deserves to be remembered and made a Tottenham legend.
33 years is not a death sentence, look at Ronaldo who at 40 continues to play just as well, but in any case
, it is Son's decision, if he decided so, it means he feels that it is time. Kroos, by the way, also ended his career earlier than expected, and Modric continued to play much longer, so it is not so much about age, but about feelings, how much you feel that you are ready to continue playing at this level. Son understands that this season will be difficult, in addition to the EPL there will also be the Champions League, and maybe that is why he decided to leave.
