Inter Milan GM Beppe Marotta admits selling Achraf Hakimi was "painful".
The title winning fullback left for PSG this week in a €70m deal.
“We begin a season that will be difficult, as usual," Marotta said.
“We are proud to unveil our new coach because the Inter project continues with a new, young and winning boss. We think he is the most prepared person and one who embodies the principles of this club.
“We are going through a difficult and in some ways disturbing time after the pandemic, also as a result of the world economy. As a reflection, football is now looking for a sustainable model.
“Surely, Inter want to continue on the same path as last season, looking at the economic and financial aspects. The owners want to build a competitive team, they've invested over €700m and football is paying the consequences of what has just happened.
“It's unthinkable to ask for the same efforts. We made painful choices like the one of selling Hakimi but always trying to give continuity."
