Bournemouth 0 Arsenal 2 Arsenal re-established themselves as serious contenders for their first Premier League title since 2004 with a comfortable victory at lowly Bournemouth on Sunday. A first win in four games took them level on points with second-placed Tottenham Hotspur, their bitter local rivals who have a superior goal difference.
After more than five hours without a league goal, Arsenal scored two in little more than a minute midway through the first half by Mesut Ozil and Alex Oxlade-Chamberlain.
Arsene Wenger's team are still five points behind leaders Leicester City but play at home to them next Sunday.
It was their first league win since January 2, since when they had played two goalless draws and lost 1-0 to Chelsea.
"It was a must-win game for us today," Wenger told BBC Sport.
"Leicester have made a big impression in the last week after their results. They suddenly become the favourite in the Premier League and it makes our game (next week) a big game."
Welsh midfielder Aaron Ramsey was heavily involved in both goals.
