We don't really seem to get good results against you away from home in recent times, so I'm actually quite glad we're at The Emirates. I know your record at our place isn't great either, but it is a cup game and anything can happen.
We have Huddersfield Town at home on Saturday 8th December, Qarabag at home on Thursday 13th December (though I suspect Emery won't field a strong XI), Southampton away (where our record isn't amazing) on Sunday 16th and then we play you lot on Tuesday 18th December.
To be brutally honest, I don't have a clue what team Emery will field!

On the one hand, he will understand the importance of the north London derby. On the other hand, he can be quite pragmatic with his team selections.
Baring in mind we're playing you earlier that month as well.
Losing to Spurs always hurts and I'd like to think we are capable of winning both games. But if I was told that I could choose which game to win and which one to lose, I'd prefer to win the league game over the cup one, as I don't really care much for the League Cup.
