Not for me.They achieved 100 points with mainly Orta and Stones 2 seasons ago, so add Laporte to the mix and they don't have that many worries. Plus Ferna is more than capable of playing at the back. Walker isn't good enough for CB. He's too error prone and struggles sometimes with basic passes out from the back. His reading of the game is below par for whats expected for that position.
Aguero will be tough to replace. I wonder if Icardi can be that man? There aren't that many top quality options out there for centre forward.
Recently we've tried to bring in good players with stable backgrounds.
Icardi while talented has too much baggage.
