SWANSEA, Wales — Mesut Ozil set up two goals as Arsenal used a second-half barrage to beat Swansea 3-0 Saturday in the Premier League.
The win helped Arsenal bounce back a loss to Sheffield Wednesday in the League Cup as the Gunners shrugged off their many injury concerns to seize back some momentum going into a crucial Champions League trip to Bayern Munich.
After a hesitant first half, Olivier Giroud broke the deadlock by heading in Ozil's corner in the 49th minute for the 2,000th goal Arsenal has scored under manager Arsene Wenger.
Laurent Koscielny then doubled the lead in the 68th despite protests from the home team that Giroud had fouled goalkeeper Lukasz Fabianski in the buildup, and Joel Campbell marked his first Premier League start by slotting in the third in the 73rd after being set up by Ozil.
The win keeps Arsenal tied with leader Manchester City, but still behind on goal difference.
"We needed this win before the big game on Wednesday," Giroud said. "We started slowly but we created chances to score. But needed to wait until the second half to put them in."
Campbell was given a start on the right wing with Aaron Ramsey, Theo Walcott and Alex Oxlade-Chamberlain all out injured — joining long-term absentee Danny Welbeck — and the Costa Rica striker rounded off the win with an emphatic finish.
Swansea had the best chance of the first half when Bafetimbi Gomis was sent through clear on goal and rounded Petr Cech, but Arsenal defender Hector Bellerin used his speed to track back and make a sliding challenge to clear the ball just as Gomis was about to slot it into an empty net.
