This is very surprising news, as we hadn't heard any rumors about Son before. His departure will leave a huge hole in Tottenham squad, one that will be very difficult for any other player to fill. Son has played for Tottenham for a decade, and his decision to move to the MLS was indeed the right one. Son played his final match against Newcastle in a friendly in Korea, a very emotional farewell.
I don't see Son's move to the MLS as the right decision, and it's especially surprising because there were almost no rumors about Son leaving Tottenham.
The question is why Son moved to the MLS, as he should be able to play in a much more competitive league and still achieve the best of his career.
Some say age is a factor, as the Premier League is highly competitive, which can affect a player's performance. However, considering Son's abilities, he may still have plenty of potential to play there in the next year or two.
This is a difficult decision for Tottenham, as they will need to find a suitable replacement in the near future.
