The 29-year-old has been with Porto for four seasons and has an impressive return of 62 goals in 131 games.
However, his contract runs out in June 2021 and Porto have no intention of renewing it.
With that in mind, they are open to cashing in on the Brazilian marksman this summer, alerting Torino.
The initial request from Porto is €15m, a reasonable figure due to his contract situation.
Tiquinho has a release clause of €40m, but Porto know no one will pay close to that.
Torino sporting director Davide Vagnati is seriously thinking about this option and could open talks with Porto in the next few days.
Vagnati has already spoken to Tiquinho’s entourage to evaluate the pros and cons of a possible negotiation.
Tiquinho’s hypothetical arrival is not linked to the future of Andrea Belotti, Torino’s much sought-after striker.
Instead, it is Simone Zaza who could be sold to make way for Tiquinho.
