Are we using hind sight to criticise our signings

I'm not talking about the signings we didn't make. Its more the ones that haven't really worked out (yet)

Ducksch good record in the Bunders
Kyogo excellent goals per game record over a number of years
Neumann widely recognised as one of the best CH in German second Division
Beadle. Koumas, Cashin, all rated highly enough by Premier league teams to still be on their books.

Hind sight is an exact science, are we being harsh on our recruitment
