Now a free agent, Cassano has been linked with a number of clubs, and Allegri - who worked with the striker during his time at San Siro - could not hide his admiration for his quality.
"I don't talk about players from other teams, although at the moment Cassano is no longer in another team," explained Allegri in a press conference.
"At the moment we have five strikers in attack, and at the moment no-one else has come in.
"Cassano is a player I coached at Milan, who fortunately was crucial in the Scudetto race. He's a player who has great quality on a technical level.
"I only speak about the players I have available, and then those who arrive I'll speak to when they get here.
"We'll see what opportunities there are before doing anything else, but we're alert to that, we don't need to worry and we can just think about the next game, which is tomorrow." - Allegri from a Goal article
