Asked to assess Inter's summer market campaign, Fabbri says they're weaker this season for the sale of the Cameroon international striker.
He told TMW: "Inter have taken (Mauro) Zarate in the end, but he will not be able to change the flow of the team.
"The Nerazzurri held (Wesley) Sneijder, but they are weakened by the departure of Samuel Eto'o. If they had lost Sneijder also, along with Cameroon, the situation would have been worrying.
"Eto'o could not be restrained, because the leadership need to meet their budgets also."
