Agent Silvio Pagliari has urged Italian football to take advantage of the Saudi Pro League's mega spending.
Pagliari feels Lazio president Claudio Lotito set an example of how to work the situation after selling Sergej Milinkovic-Savic to Al-Hilal.
He told TMW Radio: "We're all a little scared but for me it's a great opportunity to get rich.
"If they bring you 40 million euros for Milinkovic-Savic one year before the deadline, Italian clubs must be ready immediately to take on another profile like him.
"For me it is absolutely an opportunity and those like this must be seized, as Lotito did. And I have doubts when faced with those who tell me that it will be a soap bubble..."
