6. Inter Milan
Inter were able to rake in a significant sum when then sold Zlatan Ibrahimovic to Barcelona in 2010, with this deal the second most lucrative in transfer history at the time.
Barcelona paid €46 million to bring Ibrahimovic to the Camp Nou, while Samuel Eto’o was included in the deal to take the total fee of the transfer to €66 million.
The sale of Ibrahimovic was the most sizeable that Inter have completed by some distance, and ensures their transfer income since 2008 has been the sixth highest in Europe.
