"I like the analogy made by President Silvio Berlusconi with high tides and low tides," Galliani said. "I think it gives the perfect picture of the current situation of a team who won the Club World Cup last year.
"Listening to the whistling during the first half against Atalanta it seemed as if Milan hadn't won anything for five years, but we have won an incredible amount of trophies.
"These days, there is a tendency to forget things quickly. I'm not saying that the last 22 years should be remembered, but at least the last 12 months."
However, Galliani accepted that there are problems within the club that need to be ironed out.
"Is everything ok then? No, not at all," he conceded.
"I have enough experience to realise that there are some problems and some first half performances have been especially unconvincing. But that should be discussed privately with Carlo Ancelotti and the players.
"I'd just like to remind everyone that a club as experienced as Milan have what it takes to get through this low tide."
