Mesut Ozil was the difference maker as Arsenal were made to work hard before securing a flattering 5-0 victory over Huddersfield Town at the Emirates on Wednesday.
Germany international Ozil made an emphatic return to the starting line-up after sitting out Sunday's 1-0 win against Burnley due to illness, providing two assists and scoring another in the space of four second-half minutes to emphasise his importance amid ongoing uncertainty over his future.
Alexandre Lacazette gave the Gunners an early lead but they failed to kick on and afforded frequent chances to Huddersfield, who saw Steven Mounie's deflected shot in the second period pushed against the crossbar by Petr Cech.
Olivier Giroud replaced Lacazette at half-time, leading to concerns the former Lyon man may be carrying an injury ahead of Saturday's meeting with second-placed Manchester United, and turned home a pass from Ozil to relieve the rising anxiety in north London in the 68th minute.
The shackles came off for Arsenal and Alexis Sanchez slammed home a right-wing cross from the Germany international, who capped off a blistering spell by dinking Aaron Ramsey's throughball over the onrushing Jonas Lossl for 4-0.
Giroud's second gave the scoreline a deceptively one-sided appearance, but a 12th successive home Premier League win provides the ideal preparation for a clash with United.
