"There was a blackout," admitted Ibrahimovic. "But we are looking at it in a positive light. We need to understand how to reawaken.
"It's still not finished in our heads even if we are top of the table and need to recharge our batteries."
The 27-year-old striker then turned to Manchester United, who Inter face in the Champions League next month.
"They are two games that will count a lot," said Ibrahimovic. "We will play against what is perhaps the best team in the world, but I believe it will be a balanced challenge."
