Serie A's biggest clubs are eager to bring the former AC Milan starlet back to Italy in 2026.
La Gazzetta dello Sport says Juve will make their move in January by proposing an exchange involving Canada striker Jonathan David for Tonali.
David joined Juve in a Bosman transfer from Lille over the summer, but he has struggled to adjust to life on and off the pitch in Italy.
Juve are eager to shift him out and have spied an opportunity to use David in negotiations for Tonali over the winter market.
