The Sweden international believes that the Rossoneri will not be able to invest big in summer signings, but stressed that he will not leave the club
Massimiliano Allegri is looking to fine tune his side in the summer after the Rossoneri failed to retain their Serie A crown, finishing four points behind champions Juventus.
Riccardo Montolivo and Bakaye Traore have already been confirmed as reinforcements for 2012-13, but Ibrahimovic believes that Milan lack the funds to make the proper adjustments to the squad.
"Milan's problem is an economic one," he told AftonBladet. "We do not have the money to buy five players, or those that we need.
"We have already signed two players, maybe a third will come.
"It is also true that the more you play together, the more you can improve as a team. That is the case of Chelsea, who were not the strongest side."
Questioned about his future, the Sweden international stated that he has no plans to leave San Siro, despite reports linking him with Manchester City.
"I am fine at Milan and I will respect my contract," he said. "A lot can happen, but right now nothing has happened.
"I will respect my contract with Milan."
