Who are top strikers? Lewa, Benzema, Kane, Haaland, Mbappe...? none of those will come at this time.
Icardi, Belotti, Vlahovic, Jesus, etc are the range can hope for, any of them would be an upgrade to Morata at least. A player that can play from the left wing would also be very useful.
If Ronaldo was going to leave he should have said it early and maybe we could have been in for Depay. Would have been a great option for our system.
