Arsenal
Petr Cech - 7/10
2 saves, 1 punch, 2 jump catches and a decent game overall for Petr Cech. His defence did save him a lot of trouble this evening.
Nacho Monreal - 6.5/10
Had a good back at the back but Monreal was often brushed aside with ease and needs to plant a firmer foot if he's to really make a difference for Arsenal's defence against some of these typically 'British' sides.
Shkodran Mustafi - 7.5/10
Easily one of the better defenders on the day again but was often victim to Ashley Barnes' ground-hogging techniques. Had one key pass to his name, again.
Laurent Koscielny - 8/10
Arsenal's best player of the day. 8 clearances, winning 6 of his 7 duels, a 90.2% pass accuracy and two key passes all made that last-minute winner from Sanchez so much so sweeter.
Sead Kolasinac - 6.5/10
Did more offensively than defensive but given Arsenal's system currently, it's no surprise he often saw himself in the box with his dribbles and his overlapping runs.
Granit Xhaka - 6.5/10
Not the best of performances from the Swiss and has often struggled with sides that bully him but did create one chance and should've had more if not for the wall ahead of him.
Aaron Ramsey - 7.5/10
God, this man runs a lot. Arsenal's most hard-working player again this time with 11.69 km against Burnley means Ramsey is a threat unlike most other midfielders in the Premier League.
Hector Bellerin - 6.5/10
Not a usual Bellerin-esque performance from the Spaniard today but did contribute in the final third more than he did where he's from. Can improve.
Alexis Sanchez - 8/10
Surprisingly didn't give away the ball as often and has contributed to five goals in his last six Premier League games thanks to the final penalty in tonight's encounter. Will be missed for the second part of the season.
Alex Iwobi - 6.5/10
A 91.3% successful pass percentage the only positive from Iwobi's game. Did take the ball smartly when needed but didn't do enough to create clear-cut chances in the final third - something the man he replaced - Mesut Ozil - would do better.
Alexander Lacazette - 7/10
He's finally getting the attention he deserves in the Premier League. His runs are excellent and he's a true threat for Arsenal unlike most of their other recent strikers.
Substitutes
Jack Wilshere - 6.5/10
Adds that fire when he comes on and did just that again for Arsenal. Will be glad he's being introduced earlier than usual in Premier League games.
Danny Welbeck - 6.5/10
Ran around, closed down and made 1 pass which was successful. Technically, the only player on the pitch with a 100% pass percentage rate. Pretty awesome, right?
