Mesut Ozil inspired Arsenal to reclaim top spot in the Premier League, at least for 24 hours, as they won their first league meeting with Bournemouth.
After a tense opening, Ozil's corner was met with a firm header by defender Gabriel for his first goal in English football.
Ozil made it 2-0 after the break from a slick one-two with Olivier Giroud.
Bournemouth showed plenty of spirit, but could not find their way through as Arsenal closed out the victory.
With Leicester not playing until Tuesday, Arsenal leapfrog them into top spot by one point.
Bournemouth, meanwhile, slip to 16th and remain only three points from danger as their six-match unbeaten run came to an end.
