It looks as if Juventus will not take up their option to make his move permanent after spending the season in Turin on loan.
"The issue with Juventus is not definitely closed. They asked for a few days to think about it, but it's only right for me to seek other options at this point," agent Franco Zavaglia told Sky Sport Italia.
"If we can't find any other alternatives, then the player will return to Liverpool."
Milan have been linked with a swoop for the Italy midfielder, but the representative insists they aren't the only ones.
"Milan? Alberto can play in all the top level clubs. There could be interest from Inter and Napoli too, but we have to see the technical requirements of the sides. For instance, right now Napoli are pushing hard for Gokhan Inler.
"It's only natural that Alberto wants to stay in Italy, but he also gets along well in England and the fans admire him."
