Cesc Fabregas and Carlos Vela scored two goals each while Andrey Arshavin and Marouane Chamakh scored the other goals.
“The speed and the technique of our game and the collectiveness, pace, technical quality and movement was outstanding,” Wenger told Sky Sports.
“Overall, defensively we looked quite sound for a big part of the game because Braga can score goals.
“I enjoyed it very much tonight because the game was nearly never in doubt and it was really enjoyable to watch your team playing with high pace and give some pleasure to the fans.”
