Hernandez, Arnautovic and Wilshere aren't giving you 30+ performances a year (in Wilsheres case, he isn't getting on the pitch that many times, never mind having form over it).
Yarmolenko is an absolute roll of the dice, let's not pretend we know which way it will land.
Defence doesn't look cast iron to me either.
Now, don't get me wrong. I appreciate every West Ham fan would look at our team (Pickford, Baines, Keane, Holgate, Coleman, Gana, Schneiderlin, Sigurdsson, Walcott, Lookman, Tosun) and similarly dismiss it in the way i have done above.
But that just shows how far behind us they have been over the years that this genuine improvement of theirs have put us them in our sphere.
