Juventus GM Beppe Marotta feels this summer's mega spending will only increase next year.
Juve fought off huge offers from Barcelona and Chelsea during the transfer window.
Marotta said, “What I've noticed is that we're in a particular market, and next year values will increase by 30 or 40 per cent.
“I've noticed how the Premier League has become richer, and we've seen clubs buying players for what would have been crazy prices until recently, but are very normal today.
“Next year I predict even bigger deals. If Pogba maintains his level of performance from last year, then €100m will not be enough to get him."
