I disagree with Lippi here, only because of the fact that the market and our image back then were very different than it is today. There are more players with inflated price tags, than back in the day. For e.g. Zizou was probably the only player at that time with that kind of value and price on his head. Today Pogba is closely followed by the likes of Lewandowski, Muller, Neymar (who'd cost more), all having that kind of pricing. So the lower grade players than these guys, are naturally more expensive than they also ought to be, factoring in how inflated these guys prices are. Add to that, Juve is still working on their european image with the post 2000 generation of fans, and players alike. So it probably won't be as easy as people think to buy with the Pogba money. Sure, we may get a Cavani and an Isco too, but unlike in 98, we would have 10 other clubs that would be just as attractive to our targets, and those 10 other clubs would have just as much ability to outbid us, if not in transfer fees, then in salary.
For me, Juve's best bet is holding on to the likes of Dybala, Pogba and Morata, and the likes of Sandro etc. and build a solid core around these guys to create a bright and European centric future as far as titles go. Selling these guys is going to throw us into the same vicious cycle of buying the next potential big thing and waiting for the pay off as they mature before they discover the greener pastures of the La liga and EPL. Wrong way forward IMO, if we truly want to be annual contenders for the CL.
