Arsene Wenger was in the stands as he is in the midst of a three-game touchline ban and his man on the ground, Bould, knows the 3-1 scoreline flattered the hosts.
"We've won the game, it is a great result for us," the assistant coach said. "We made it tough.
"They were actually, I thought, very good. Their organisation was excellent and they made it tough for us.
"I think we improved in the second half with the ball, but we looked a little bit nervy, I have to say, at times and overall we are delighted.
"I think it probably affected our confidence a little bit getting beat when we felt perhaps - even though we didn't play so great - we should have got something from the game.
"Maybe there was a little bit of a carry-over, but we're hoping now that we've won that has gone, done and dusted, and we get back on track."
