I'm not sure where this West Ham opinion that they failed to strengthen after selling Payet comes from.A couple of posts on Skyscrapercity by a West Ham fan, who is a good poster there.
And when question on the bung statement :
Payet was lightyears ahead of that club, players like him grace clubs like that once in a generation. How could they possibly have done better when all they have to attract players is a relegation release clause? Arnautovic is about the top level of player they should be aiming for.
