We picked up a "struggling" Skippy. McCormack couldn't hack it with Rangers. Dom Thomas was "too wee" for Celtic. Ojamaa couldn't make the step up from Derby's Academy side etc. etc.
Sometimes players a mince, other times they are just a bad fit for a team, sometimes a bit of both.
I'll be really happy when the season starts, though, and we can start slagging off players in competitive matches.
