It's been widely suggested that Arsenal should look to restore their faith in the back four but Arsène Wenger stuck with his plans, and they managed to go their first game of the season without conceding.
Arsenal got back to winning ways against a Bournemouth side who are still yet to register a point this season.
Manager Arsene Wenger has already come in for criticism after a slow start to the campaign, having been challenged to deliver major silverware following his contract renewal in May.
Ozil shone for his country during the recent worldwide break but just can't seem to get into the same groove for Arsenal this season, and questions must also be asked of Wenger, who continues to use him in a role that doesn't get the best out of him.
Welbeck calmed any nerves with a sixth-minute opener before sweeping home a well-taken second after a wonderful Lacazette strike had made it two. "Well, I believe that we were on the case past year", Wenger said. He gets stronger and stronger. What better opponents to play for Josh King to recapture the form of last season, which saw him score 16 goals in 36 appearances.
"He's a guy who has a huge physical potential". I liked his second goal today, because it's really clean finishing for any goalscorer.

ARSENE WENGER HAS changed his mind on UEFA's Financial Fair Play (FFP) rules because he feels they have become unenforceable.
"He was close to joining us, maybe closer last year than this year because the competition was a bit smaller than it is today", the French coach said.
Continuing his retaliation, the long-serving Arsenal manager said, "We have to take a distance with that as well, focus on our performance and not be dragged into any animosity".
Wenger said: "I didn't want him to leave, it's true. The interpretation of the attitudes is always very unsafe".
