Bobb?The season before Haaland we had Sterling, Gundogan and Mahrez.
We've now got Grealish, Kovacic and Doku.
The difference in quality in front of goal is a gaping chasm.
If Erling and Phil are available for the majority of the season then we'll most likely be fine but if anything happens to them then we're relying on people who haven't shown that they can do it.
