Sporting CP boss Ruben Amorim's release clause will be reduced by around 25 percent in the summer.
The young coach is highly rated throughout Europe for his exceptional work at the Portuguese club.
Tottenham are among the many teams chasing after his signature this summer.
According to The Guardian, Amorim will be available for a release clause of around 13.25 million this summer.
Spurs will likely be looking for a replacement for Antonio Conte, who is out of contract in the summer.
There is even speculation that Conte could lose his job during this international break.
