The former Bayer Leverkusen man has made an impressive start to his Spurs career.
‘Sky sources’ claim the player has settled well with his family in London and is happy with the way things are run at Spurs.
He is also thought to be a big fan of Mauricio Pochettino and his backroom staff, and enjoys their approach to football.
On the pitch, his performances have been excellent so far, with his added dynamism and attacking threat coinciding with Tottenham’s mini win streak.
The South Korean international made his debut against Sunderland last month and while he wasn’t at his best, he still provided glimpses of the quality that was to come.
He followed that appearance with two goals against Qarabag in the Europa League and the winner against Crystal Palace a few days later.
His energy was vital in overwhelming Manchester City in Spurs’ impressive 4-1 win the following week, but the game ended on a sour note with the news that Son had picked up an injury.
Pochettino suggested the 23-year old could be out for several weeks but he is expected to make a return to training as early as next Monday and should soon be in contention for the first-team.
Spurs missed his presence against Swansea last weekend - with his back-up, Nacer Chadli, failing to make an impact - and fans will be eager for the return of their new hero sooner rather than later
