Agent Mino Raiola insists it will only take crazy money to land the Italy U21 striker.
"Mario will stay at Inter. We have not received offers from any team, and Inter have not said he is for sale, therefore he will stay where he is," he told Il Corriere dello Sport.
But, when prompted, the sound of money brought him to his feet.
"Is he worth 40 million? For me he is worth more than that," he added.
"The market is open until August 30, and so anything can happen."
