Tottenham are yet to complete a signing this month.
The 19-year-old has caught they eye this season while on loan from Serie A side Cagliari in Italy's second tier Serie B with Perugia, scoring seven goals in 19 outings as well as adding three assists during that time.
Juventus are said to be interested in the three-time North Korea Under-19 international, and have "intensified" their efforts to land the forward's signature, as they are expecting competitors in pursuit of the striker.
Now, Spurs are set to provide that competition after being alerted to Kwang's form in Italy, with the report stating Tottenham are keeping the versatile forward under "close observation".
Kwang can play in a number of positions but is best suited as a striker, although he has impressed for Perugia on both flanks, in the number 10 role and as the second-tier's attacking spearhead.
It remains to be seen if Spurs will make an offer for Kwang, as they look to beat Champions League Round of 16 opponents Juventus to the North Korean's signature.
