Quaresma joined Inter Milan in a 30.6 million euros deal.
“For now I am not convinced,” Dossena told the Gazzetta dello Sport.
“There is a question mark next to Quaresma. He did not have a great Euro 2008.
“I would like to see him on the field, I am curious.”
He added: “I like Poulsen and Mellberg (of Juventus), they are two excellent purchases.
“The two best signings? Above all, Ronaldinho (for Milan). He is still finding his way back but he is the number 1.
“Fiorentina have made a great purchase too in buying Felipe Melo (from Almeria).”
