Barca and Inter have been in marathon talks over the Argentina international, with the Nerazzurri demanding a deal worth the equivalent of Lautaro's €111m buyout clause.
But Quilon says: "I find it hard to believe that FC Barcelona invests in Lautaro.
"I think Barça and Madrid are going to spend little."
In his opinion, “the market will drop 50% in transfers. There will be loans."
But he added, "There will be about six major operations."
