Only way i see us bringing in someone else would be if Lopez flopped horribly or if one of Immobile, Gabbiadini really impressed over the second half of the season.
So for next year it'll be Lopez, Llorente, Vucinic, Giovinco, and then a big signing striker. That's a pretty awesome overhaul of the striker force. gio will be the fifth choice obviously and i'm ok with that.
