Yes Aguero is a pipe dream.
Honestly, I am not just saying this as a Juve fan, but I find it very sad that PSG, Monaco and Manchester City are around with their recent money. Just think about how many players they got from Serie A in the last few years - and a lot of that had to do with the fact that Mancini and Ancelotti took them. Then on top of that, how many of them took away our targets. The list is truly disgusting.
Off the top of my head:
Man City & PSG from Serie A: Kolarov, Kompany, Lavezzi, Pastore, Ibrahimovic, Cavani, Jovetic, Verratti, Thiago Silva, Menez, Motta, Maxwell, Sirigu!
And then the players we wanted that were not from Serie A: Dzeko & Aguero
Those 2 clubs really sucked the life out of Serie A. One can argue that it may have happened anyway without them, but the reality is I think at least half of those players would still be here if it wasn't for PSG, City, Ancelotti, Leonardo and Mancini.
