One aspect that's probably worth noting, after all the pre-season talk about how matches would be a grub-fest, with inexperienced refs failing to protect the players - the ref actually did a really decent job of keeping the game flowing.
There were surprisingly few penalties for such a high intensity game, and very little rough stuff. Both teams deserve credit for that as well, but I though the referee had a very good game as well.
The fact that he had the bottle to award a penalty for offside in the 83rd minute was obviously a bonus
