The 30-year-old has been a regular for the Italian club this season, making 39 appearances in all competitions.
And now, according to Tutto Mercato, Leicester and Newcastle are both trying to sign the Italian.
The pair have both been scouting De Silvestri and are ready to begin talks with Torino.
The Italian club want to keep hold of the full-back, but a lucrative offer from abroad could be too great to turn down.
