Watching the highlights I actually just think it was all wrong, despite us being the more dangerous side in the first half. As pointed out by other posters there was no midfield, the spaces between players were just too vast, this made life easier for Spurs. Also the extra man in defence made our offside trap a lot worse because there's simply more players who have to co-ordinate it, therefore it was easier to get wrong, and the first goal was a direct consequence of this.
I'd love to know what Emery's thinking was. Did he really think that we had to show Spurs more respect than what we did to Arsenal and Man City or does he see that our players are not in the best condition to play like we usually do?
From the outside it looks like Emery just got things badly wrong.
