And returning to Spurs players, the current rumor is quite strong regarding Son Heung-min, a Korean player who has been loyal to Spurs for quite some time. Last season, Son's performance declined, and with several transfers made by Spurs, it's been suggested that a new player could replace Son. However, I think that, even if the player doesn't want to leave Spurs, I think the club should respect that decision, as Son has made a significant contribution to Spurs over a long period.
When it comes to professional business, names and contributions mean nothing and you can see how Real Madrid staff works. They don't care about players careers in the team and how helpful they were. Once they decline in the performance they are out, and once they get old, they get bad renewal contracts. There is many examples like Sergio Ramos and many others. I can give the example of Manchester United holding their favourite defender although his fatal mistakes and they saw the consequences.
Even if a player wants to stay, he should prove himself with the team otherwise he is taking the place of another player and sometimes 2 or even 3 players depending from his wage.
Back to Son, I think another chance this first half of the season could give every party a clear view about his future within the team.
