No they don't. Sebo didn't, Murray didn't, Sionko didn't, Svensson didn't.
Just because they are in the squad doesn't mean they should have some aura around them that means they are should be untouched by the hand of criticism. Players who are perfoming get credit, those who are not recieve criticism.
It's the same in any workplace, football should be no different.
if u work in a cake factory and ure job is to put the cherries ontop of the cakes u wouldnt expect to be critised for a dodgy sponge,boyd paid to score goals and thats what he does
and he does that well most of the time.
but this team now needs a more complete striker than him. I'm sure he'll do well in the SPL when he gets his chance but in europe, no.
