I'm not sure that's right on Vardy. He was barely noticeable against Cov at home, similar Vs Hull except a header.
Iheanacho I have highly rated previously, I'm not quite sure what's happened to his finishing though, although Friday was the first massive chance I'd say he has missed this season.
I'd say Iheanacho has a lot of work to do, but I also feel if he gets one he could have a purple patch. The new system is going to take a while for him. At one point under Rodgers he was the only player who could create or score out of nothing.
I would like to see both Vardy and Iheanacho together but have accepted it's not going to happen with Enzo
