The Premier League side are reportedly looking to submit a bid of around £17 million for the defender, and Tomiyasu certainly has the talent to justify that outlay in the long run.
It is evident that they will need more than one centre back, and Tomiyasu could prove to be a superb long term acquisition.
The Japanese international can operate as the right pack and a centre back. Nuno Espirito Santo could use a quality and versatile defender like him in his side, and the Japanese is reportedly open to the transfer as well.
The player was on international duty because of the Olympics, and his future could now be sorted soon.
The Japanese international is still quite young, and he is likely to improve in the future with experience and coaching.
If he manages to fulfil his potential with the London club, Spurs could have a bargain on their hands.
