Five things we learned about Arsenal this weekend

Arsenal fans have local bragging right once more, after the Gunners beat Tottenham 1-0 in the first north London derby of the new campaign. Although it not being the polished performance that the Emirates Stadium faithful would hope for, the three points will be welcomed by Arsene Wenger . Here are five things that became apparent about Arsenal in their victory. Ramsey can be a world beater The Arsenal midfield were always set for a challenge when Tottenham came to the Emirates, as Paulinho, Mousa Dembele and Etienne Capoue were selected in the Spurs iboiler room. Despite the international calibre of his opponents, Aaron Ramsey was the best midfielder on show. The Wales international mixed his trademark lung-busting runs with a combativeness and range of passing, and has had a wonderful start to this season. Ramsey is a key man for Arsenal and can be a star for the side. Koscielny’s importance to Arsenal Laurent Koscielny returned to the home side’s back four and put in a no-nonsense performance to show his importance to the team. Per Mertesacker has certainly improved after a shaky start to his time in England, but Koscielny is the side’s defensive leader. He dealt with Soldado well and made a number of important challenges and clearances. Even when Thomas Vermaelen returns to fitness, the France international must play for the Gunners . Gibbs a testament to the Arsenal youth set-up Kieran Gibbs got the nod over Nacho Monreal at left-back and put in an accomplished and assured performance in the Arsenal defence. Many will expect the Spaniard to be first choice when fully fit, but Gibbs showed that he has the ability to be a consistent starter for the side. Gibbs was caught in a two-on-one situation a number of times and did well against Andros Townsend and Kyle Walker. The youth product could well be a mainstay for Arsenal at left- back this term. Giroud worthy of lone attacking role Olivier Giroud had an up-and-down debut campaign in England last season but is starting to show just why Arsene Wenger brought him to the club. His fourth goal in as many games settled the clash in his side’s favour, while his all-round play was impressive. Giroud can be the main attacking threat for Arsenal for the remainder of the campaign and looks much more confident than he did last term. Wenger lacks options Comparing the Arsenal bench to that of their opponents, the home side lacked real experience or proven quality in their replacements. Arsenal fans will hope that the club will be busy in the transfer market today to add an extra player or two to help cope with injuries or unavailability.
