Lazio chief Igli Tare has taken aim at Inter Milan as they push to complete the signing of Stefan de Vrij.
Off contract in June, the Dutch defender is said to have already agreed Bosman terms with the Nerazzurri.
Asked about the situation, Tare stated: "The relationship with the Milanese professionally is positive, with Milan we have a great relationship.
"(Marco) Fassone as that with (Massimo) Mirabelli, we showed it with the (Lucas) Biglia deal.
"We did not receive any calls for de Vrij with Inter, we learned it through different channels. This is part of the game, but the relationships are excellent.
"Inter's behavior? At certain levels, in my opinion, things are done in another way."
