Inter president Massimo Moratti has insisted that the club were unable to hold on to Samuel Eto'o and Thiago Motta.
The Cameroonian striker signed for Anzhi Makhachkala last summer in a deal reportedly worth €28 million, while Motta joined Paris Saint-Germain in January for €10 million.
Inter's transactions in the transfer market has been the subject of much criticism as the club sit fifth in the Serie A table, but Moratti stressed that they were helpless in preventing the duo from leaving.
"I think I am an Inter fan and if some players left, it is because the conditions to keep them were no longer there," Moratti told Corriere della Sera.
"Nothing was done accidentally or superficially, we always considered the needs of that particular moment."
The Inter supremo then admitted that his side may have taken some wrong turns, but noted that the fans' unhappiness is explained by the club's success in the last few seasons.
"It is possible that we have made some wrong decisions," Moratti explained. "But I do not think we made many errors, or even serious ones.
"The problem is that we had become too well-accustomed: in the last years we found players who were able to quickly enter the mechanism of the team.
"Football is not maths and strategies, as a renewal which seemed correct sometimes do not deliver the results that you wanted."
