Sarr, 21, is an attractive free agent option for clubs after leaving Nice at the end of his contract.
Torino recently opened talks for centre-back Sarr and are still pushing to get a deal done.
But Arsenal yesterday stepped forward with an interest in the player, which could complicate matters.
Sarr, who made 119 appearances for Nice, has a market value of €16m.
Esposito a loan option
The 19-year-old striker is about to renew his contract with Inter and they want him to gain experience.
Torino are a prime candidate to take Esposito, who has already made seven Serie A appearances for Inter.
