"Once we are in front the teams who usually defend against us have to come out and that gives us space to develop our game even better," he was quoted as saying by The Sun.
"That shows you that when we start our games in a positive way, we can dominate. It highlights just how important the confidence is to go into the games and to have a strong start.
"Our team has always developed a way to play that makes them stronger throughout the season."
Arsenal sit fifth in the Premier League table, two points behind Tottenham and Chelsea in the race for fourth but holding a game in hand over their north London rivals.
After Norwich, they face Everton, who still hold faint hopes of finishing in the top four, before rounding off their season with matches against Fulham, league leaders Manchester United, QPR, Wigan and Newcastle.
