Inter Milan president Erick Thohir says improving the club off the pitch is as important as new signings.
The Indonesian bought the club last season.
"The most important thing for me is to try to make Inter more competitive, not just on the pitch but off it too," Thohir said.
"Obviously, to make the team competitive we need the players, the Coach and the technical staff.
"As far as the economic side goes, the non-sporting side, I want to make sure Inter's revenue increases in order to make us competitive in the transfer market.
"I'm giving it two to three years of transition for our revenue to increase. However, we have also signed Hernanes, D'Ambrosio and Vidic.
"Other reinforcements? Definitely, but we cannot be reckless and incur problems with financial fair play."
