On the whole he's been very good for us this season. But if we fail to find the goals on Tuesday I feel his spell with us will end on a sour note.
Yes the ref was very poor today, but he was pushing it with his gentle stroll to take throw ins, even after being warned. He even could've done that fake "I'm pretending to run but actually I'm still walking" thing, but he didn't. And the same with Gibbs, if you go diving in, even though there's no intent, you put yourself in a risky position. So he can't really complain.
If we do fail to find the goals though, it won't be his red card alone that cost us promotion.
