“I felt that to lose would have been terrible for us because we had such good preparation and to sit there on Saturday morning and think we had lost at home would have been terrible,” Arsène Wenger said at full-time.
“It is a relief and I believe as well a reminder to the players that they have hurdles on the way and that we can get round it, like tonight so that is quite positive.
“After that, let's take it game by game - go to Stoke - then to Liverpool, who are as well one of the teams who want to win the Premier League.
“To win like we did will only strengthen [the belief] and overall we have good ingredients in the squad and it is a good opportunity again to show it away from home.”
The manager was pleased to see Sead Kolasinac mark his first Premier League appearance with an assist for Danny Welbeck’s goal.
“His performance talks about him and the way the crowd responds shows he has been straight away been accepted and shows you can still find good players on the market for free,” Wenger said.
“For me it is important to build the game out from the back, sometimes I am punished for it but it has to be the basis of our game. If you want to play football you have to build the game out from the back.”
