To me this link is first and most primarily interesting because this has become news. Why would this become news? I don't think that this sort of stuff is news when it comes to other players say in other clubs. And what does it mean that this has become news? And who has made it news? How did this Fabrizio Romano find out that this is happening? Did it come from the club or did it come from the player's agent?
If this came from the club, why would the club make this a news item? What purpose would a club have unless the club wants to perhaps sell the player?
If this came from the player's agent, why would the player's agent make this a news item? What purpose would a player agent have unless the player wants to perhaps leave the club? Or at least check such possibilities/options out?
As a Spurs fan I have watched the last Spurs game vs Ipswich very intently. I noticed that Son was unhappy. I don't know why exactly he is so unhappy but it perhaps has to do with him being used very wide on the left side. I think that Son is a very direct player that likes to be directly involved as much as possible. And I think he is also frustrated with the fact that Solanke has taken up that role. I don't think that Solanke and Son have started on the right footing, so to say.
And here is one example of Son playing on the left. Notice how he is not using the player next to him well. That is a very inefficient football play that I suppose a manager like Guardiola would not tolerate. This inefficient play has I think come about because of Son's frustration:
But, Son can also be great on the left. He put in a fantastic cross that turned the Spurs previous game vs. Villa which Spurs won 4:1.
Son, I think, is a great player who could help a team push for a title. He is a great goal scorer and he is very direct. He could be a great addition to a team chasing a championship (as a member of 5-6 players who are rotated to play a position in the front 3). But that would have to be a team that would suit his very direct style of play.
Tottenham, sadly, is a club riddled with problems. Very, very poorly run and in that I don't include the manager. Son is the captain and I consider him to be the best Spurs player. He still appears to have great stamina, directness and explosiveness but he is getting there in terms of age.
