Dossena admits he was happy seeing Toro swoop for Casadei from Chelsea.
He told La Stampa: "I saw them very well, they will have an important weight for the end of the season. They are a pair that complete each other: one methodist and distributor, the other more physical, running and depth.
"I have seen many excellent footballers become shooting stars, but I don't think this is the case. They seem like guys with their heads screwed on."
Dossena concluded by focusing specifically on Casadei's qualities: "I was kind of expecting this approach, he comes from an experience in England that did him good. He has quality, he is certainly a player with a future and at this rate he will soon reach the blue jersey. Torino has made a great move."
