Yeah, he was unlucky. And, yeah, I'd say either him or Hannibal were our best player at that stage - and definitely Hannibal by the end.
Watching him at youth levels, Gore has always been one to make the odd rash tackle in midfield. He's always felt similar to Hannibal to me: both good all round box to box CM's with a mix of technical attributes, energy and a fiery, competitive side to their game.
So when I saw the tackle first time, I was a little worried that he'd gone in hard and it could be a red. But, on the replay, that was a disservice to him as that really shouldn't have been a red card.
