Staveros tweet sums it up:
The way we went deep you'd think we were playing Barcelona, not Spurs minus some of their best players
And quoting him about sums up your knowledge of the game.
Spurs at home, down by 1 are always going to have more of the ball no matter who they play. In fact, Walker's run was because we had committed men forward, he had space to run into, Baines made a very poor defensive play and they got their chance.
The only mistake I can see from Moyes was not finding a way to help Baines deal with Walker who ripped him apart all game.
