According to a report in La Repubblica, all Serie A teams have signed more than 40 players over the last 12 months, up from just six a year ago.
The report states that the number of players signed during that time has now reached 70.
There is no official number of those who have already signed for next season.
This number, of course, is subject to change, but according to the report, all are on a €200,000 (about £155,000) per week contract.
This includes the players signed in January and February.
The report says the number is likely to be even higher next season, due to a number of factors, including the new signing bonus.
The bonus is a significant sum for any team, especially one as expensive as Milan.
Milan are the only club to have signed over 40 players in one season.
