Arsenal moved nine points clear of their top four rivals Liverpool on Saturday afternoon with a 4-1 win at home in the Premier League. Goals from Hector Bellerin, Mesut Ozil and Alexis Sanchez put the Gunners 3-0 ahead, before Jordan Henderson pulled one back from the penalty spot for the visitors. Olivier Giroud completed the scoreline with a sumptuous strike in injury time. Here, Sportsmail's Matt Barlow casts his eye over the two teams' performances at the Emirates. Arsenal (4-2-3-1) DAVID OSPINA - 6.5 . No shots to save first half, although out smartly once or twice. Made a flying save to thwart Can in the second-half and almost saved Jordan Henderson's penalty. HECTOR BELLERIN - 6.5 . Scored a wonderful goal with his left foot. Unfortunate to be booked for a foul by Mathieu Flamini and then lucky not to be sent off for a foul on Sterling which conceded penalty. Hector Bellerin celebrates after putting Arsenal 1-0 ahead against Liverpool in the first half on Saturday . PER MERTESACKER - 6.5 . Coped quite well with the nimble trio of Liverpool strikers. LAURENT KOSCIELNY - 6 . Performed well until replaced early in second half by Gabriel. NACHO MONREAL - 7 . Solid defensive display, up against Lazar Markovic and Philippe Coutinho. FRANCIS COQUELIN - 7 . Offered vital bite in midfield, especially during period midway through first half when Liverpool were at their best. Alexis Sanchez celebrates after netting the Gunners third on the stroke of half-time at the Emirates . SANTI CAZORLA - 6.5 . Heavily involved in the middle of midfield, but without any of the creative frills which often decorate this game. Early shot forced a save. Hit a post late in game. AARON RAMSEY - 7 . Started very well, wide on the right. Missed a good chance after a Kolo Toure mistake and set-up Alexis Sanchez's goal with a neat touch. Faded and replaced early. ALEXIS SANCHEZ - 7 . All action as ever, including a fabulous strike before half time make it 3-0. MESUT OZIL - 7.5 . Produced silky touches and a brilliant free-kick for the second which put Arsenal in control. Mesut Ozil added a glorious second for Arsenal with a sumptuous free-kick on 40 minutes . Ozil was all smiles as he celebrated his strike in a silky personal display from the midfielder . Ozil (right) posted on Instagram after the match: 'Seven wins in a row! and so happy!' OLIVIER GIROUD - 7 . Forced early mistake from Toure which his team failed to capitalise on. Denied in the second half by a good reflex save. Scored the fourth with another stunner. SUBS: GABRIEL (for Koscielny 49 min); FLAMINI (for Ramsey), WELBECK (for Ozil) Subs not used: Macey, Gibbs, Rosicky, Walcott. MANAGER: ARSENE WENGER - 7 . Wonderful first half for the Arsenal boss, but his team do not have the knack of killing a game. There will always be chances to score. Sent on Flamini in a bid to protect the clean sheet, but Liverpool got one back. Olivier Giroud (right) added a late fourth with a brilliant strike to complete the scoreline for the Gunners . Liverpool (3-4--2-1) SIMON MIGNOLET - 5.5 . Beaten three times in eight minutes before the break, but made fine early saves from Santi Cazorla and Aaron Ramsey as well as a splendid reaction save from Olivier Giroud in the second half. EMRE CAN - 5 . Not comfortable on the right of three centre-halves or at right-back where he played after the break. Sent off for two yellow cards, the second a stupid tackle from behind on Danny Welbeck, near the corner flag. Emre Can (right) was sent off late in the second half for Liverpool to compound a miserable afternoon . Liverpool's Kolo Toure (centre) had a torrid afternoon in defence on his return to his former club . KOLO TOURE - 4.5 . Error-strewn performance defined Liverpool’s first-half. Escaped an early mistake which gave Ramsey a chance but not others. Better in back four in second half. MAMADOU SAKHO - 5 . Erratic as if disturbed playing alongside Toure in absence of Martin Skrtel. JORDAN HENDERSON - 6 . Did not contribute a great deal from right-wing-back in the first half, but more involved when he moved forward in the second half. Scored from the spot and returned to right-back after Emre Can’s red card. Jordan Henderson pulled one back for the Reds from the penalty spot on 79 minutes at the Emirates . JOE ALLEN - 6 . Ticked over in midfield. Won some tackles and passed it well, but did not protect his defence when they needed help. LUCAS LEIVA - 5.5 . First start in two months and very sluggish and wasteful in the early exchanges. Like Joe Allen, better in second half, but the game had gone by this point. ALBERTO MORENO - 5.5 . Offered nothing in attack and unreliable in defence. Easily beaten by Hector Bellerin for the opening goal. LAZAR MARKOVIC - 5 . Flickered on the counter-attack but opted to pass to Sterling when clean through and ought to have shot. Replaced at half-time. Lazar Markovic (left) wasted a glorious chance to give Liverpool the lead and was substituted at half-time . PHILIPPE COUTINHO - 5 . Unable to impose himself. One pass to Markovic created a first-half chance. Nice touches, here and there but nothing more. RAHEEM STERLING - 6 . Bright and well poised on the ball. Movement good and influential when moved to the left after the break. Won penalty. Liverpool won the penalty after Raheem Sterling (top) was fouled by Bellering (bottom) in the second half . SUBS: DANIEL STURRIDGE (HT for Markovic) Liverpool were better with him on. 6. Subs not used: Jones, Johnson, Lovren, Manquillo, Brannagan, Borini. MANAGER: BRENDAN RODGERS - 6 . Awful first half for his team in absence of  Skrtel and Steven Gerrard. Started badly, improved a little but beaten by three terrific goals in eight minutes. Switched from back-three to back-four to try and get back into the match as well as sending Daniel Sturridge on in response. But it was over when Can was dismissed. REFEREE: ANTHONY TAYLOR - 6.5 . There were mistakes and he missed small things, but overall let it flow. Got the penalty right and the red card, but made a mess of Bellerin’s cards.
