You realise mistimed tackles are often yellow cards?
This thread should really be called 'rate how pro imps the ref was'... as if we had been on the Carlisle end of the decisions people would have been agreeing with the red card and laughing at the player for coming on the pitch before he was supposed to... and giving 8/10.
I'm well aware that mistimed challenges are often yellow cards, but it doesn't mean that the first challenge by Shackell should have been.
I give a rating on the referee based on my view of his performance, not based on the result.
