|Player||Half-time Rating||Full-time Rating|
Lukasz Fabianski: The Polish shot stopper made just one save in the match. In the 18th minute, Fabianski sprawled out to deny Carl Baker of a quick equalizer.
Kieran Gibbs: Gibbs did march forward on occasion from his left-back position, but other than a few attempted crosses, he did not make a massive impact on the match.
Per Mertesacker: The tall center-back crafted a nice flick-on to Podolski to set up the second Arsenal goal.
Laurent Koscielny: Koscielny was fairly quiet at the back as Arsenal held most of the possession in the Coventry half.
Carl Jenkinson: Of the two full-backs, Jenkinson was the more active one in attack. With the Gunners playing through the right wing a lot in the first half, the 21-year-old was able to contribute in the attack on more than one occasion.
Jack Wilshere: One of Wilshere's few involvements in the match came in the 39th minute when he picked up a yellow card as the Sky Blues attempted a counter-attack.
Alex Oxlade-Chamberlain: In his first game since August, Oxlade-Chamberlain played a solid 45 minutes alongside Wilshere in the holding midfield positions.
Mesut Ozil: Ozil had a strong start to the match as he contributed an assist on the first Podolski goal. The pass by the German cut across the box to the feet of Podolski, who finished off the perfect pass by scoring the first goal of the match.
Serge Gnabry: The young midfielder was very active in the first 45 minutes, but he could not fire a shot on goal that challenged Murphy in the Coventry goal.
Lukas Podolski: Podolski was the star of the first half as he scored twice in 12 minutes to give the Gunners a comfortable lead.
Nicklas Bendtner: The tall Dane was outdone by his strike partner, and because of that, he did not make an impact on the match. The one chance that Bendtner had in the 30th minute resulted in a whiff as he could not connect with the ball on a shot.
Fabianski: When called upon, the Arsenal No. 2 keeper made a few strong saves to deny the visitors of coming back in the second half.
Gibbs: To finish off the Sky Blues, Gibbs provided Giroud with an assist on the third Arsenal goal in the 84th minute.
Mertesacker: The first-half assist was Mertesacker's lone offensive contribution as he played a more defensive role in the second half as Coventry searched for a goal.
Koscielny: The Frenchman had the stronger defensive day of the Arsenal center-back pairing as he made a few key clearances in the box. He also challenged Clarke to move out wide on his shot on goal that Fabianski saved.
Jenkinson: Up until the final seconds, Jenkinson was surging forward on the right wing looking to create chances by way of his crossing. He also caused Murphy to deflect his shot to the feet of Cazorla right before the Spaniard scored the fourth goal.
Wilshere: The England international did a solid job in the holding midfield role and he could have had an assist in the 60th minute if Bendtner knew how to finish.
Oxlade-Chamberlain: The midfielder had a nice return to the pitch, but he will surely play better once he gets more live action under his legs.
Ozil: Once again, Ozil was the catalyst to Arsenal's attack in the final 45 minutes. Ozil's pass to Wilshere inside the box set up a chance for Bendtner before the striker did not challenge Murphy in the Coventry goal one bit. He almost got a goal of his own in stoppage time as he hit the post.
Gnabry: While Jenkinson did have plenty of runs down the right side, Gnabry also had a few good runs as the Gunners dominated the right side of the pitch all night long.
Podolski: The German forward was taken off in the 79th minute before he could record a hat-trick. Podolski did most of his damage in the first half and had an overall solid performance.
Bendtner: Bendtner had a disappointing 71 minutes on the pitch as he missed the only two chances he had to score. In the 60th minute, he had plenty of time to shoot after Wilshere provided him with a nice pass, but he failed to convert as his shot went off to the left.
Santi Cazorla: Cazorla delivered the final strike of the match off a rebound in the 89th minute.
Gedion Zelalem: Zelalem became the first player born after Wenger took over as Arsenal manager to appear for the Gunners.
Olivier Giroud: In his short time on the pitch, Giroud scored the third goal of the match from the center of the penalty area.
