While Emery changed 10 players from Thursday's Europa League trip to Kiev, for which he left his key players at home entirely, Mauricio Pochettino was working with a tired squad.
"Of course it was complicated from the beginning of the game".
Only one of Alli's completed passes was in Arsenal's half. It was very competitive.
He added that he will continue to use every player in his squad as he sees this as the best way for Tottenham to succeed. "I think the team is doing that, but it's a new challenge because we're going to play against Manchester United away, and the challenge is bigger than other matches". We're disappointed when we lose any game.
Eric Dier has admitted that losing to Arsenal in the North London derby hurt his team.
Emery praised the atmosphere at Emirates Stadium during the game, suggesting it inspired Arsenal's victory.
The Emirates was full of noise now and Torreira wrapped up the win when he got through on goal and fired into the corner with 13 minutes left after Dier had needlessly slide in.
Emery made two bold changes at half-time, with Lacazette and Aaron Ramsey coming on for Henrikh Mkhitaryan and Alex Iwobi respectively, and his decision worked wonders. They have "won" 11 of those second halves.
"In the first 10 or 15 minutes we were not good enough". "In a hard moment in the first half, we kept calm".
Arsenal, unbeaten in 19 games in all competitions, moved above Spurs into fourth place in the league on goal difference, with both teams on 30 points.
