Allegri is leaving Juventus after a trophy-laden five seasons with the Serie A club.
He has won the league title in every season he has been there along with four Coppa Italias.
The prize Juve most covet is the Champions League and Allegri has twice lost in the final.
The 51-year-old is sure to have a number of suitors – but he has made no decision just yet.
“When there is an opportunity, I will return to the bench, otherwise I will take a year off,” he told DAZN.
“If I have the opportunity to choose, I will choose a team that I like. Concrete offers? Still no. Talking about the future now makes no sense.”
