The Rossoneri president confirmed he will put an end to to months of speculation by deciding whether or not to stick with their current coach during a meeting this weekend
The 45-year-old guided the San Siro side to third spot in the Serie A table this term after a difficult start to the season, but has been linked with a move away from the Rossoneri throughout the campaign.
"I believe that I'll meet with Galliani and the coach before Sunday evening and I'm sure a solution will be found," Berlusconi told reporters.
"It won't be difficult if everyone chooses what's best for our club."
Galliani was photographed having dinner with Allegri on Thursday evening as they allegedly held talks over his future, but the Milan official was unhappy with their meeting becoming public knowledge.
"They took a photo last night and I told them not to put it on Twitter so a minute later that's where it was. That's technology for you," he fumed.
"The dinner last night was lovely and the fish was delicious. Was it the last supper? That would be blasphemy..."
Milan narrowly avoided financial disaster by clinching Champions League qualification via their third placed Premier League finish.
