He goes to a worse team, but a bigger and more ambitious organisation in long term, in these smaller scales. If you noticed, Verona barely own any of their players. Majority of them are loaned in. Their model of operation is short term survival.
While Torino can manage to keep Azzurri players in their roster (Belotti, Sirigu, Izzo the cunt) and withstand pressure to sell.
I assume Torino will allow him to sign and shape players to his system. Kinda like how Gaspa got it early on, before the mass success started.
