Wenger shouldn’t be tempted to settle for Chambers as a central defensive option
The 19-year-old had a solid game against Manchester City, generally dealing with the lively Stevan Jovetic despite his limited top level experience as a centre back. Similar strong performances in friendlies and in training has seen the former Southampton player emerge as a genuine option for Wenger in that position, but despite the promising appearances, it would be a huge mistake not to invest in another proven centre back, especially after Thomas Vermaelen completed his move to Barcelona. Tempting though it may be to put faith in Chambers, the club currently only have two recognised central defenders, and could really struggle if both are out for an extended period.
Arsenal’s need for a striker is difficult to judge
Likewise, Yaya Sanogo did fairly well in the game, especially in his play holding up the ball and setting up Aaron Ramsey for his goal, and his goal haul against Benfica proved it is less about "if" he will be become a top striker, and more about biding time. But nearly all the clubs that have won the Premier League in recent years have had a world class striker on their books. Sanogo certainly isn't that yet, and Giroud, despite his superb strike, could still profit from direct competition. It will be interesting to see whether Wenger utilises Sanchez in a more central attacking role once Ozil and Walcott return, and what effect that has on the way the team plays.
Cazorla proved that he still has plenty to offer the Gunners
In a team full of central attacking midfield talent, many predicted that Santi Cazorla would be someone that may see his playing time drop. But Arsenal's last two competitive games have shown that it would be unwise to let a player of his ability leave, and he remains one of the strongest goal threats from midfield. As arguably one of the number 10s most capable on the wing, it is likely he will be a valuable option out left.
Ramsey could be set for a massive season for Arsenal
Aaron Ramsey is probably Arsenal's best player at the moment. His work rate, skill, and improved goalscoring record make him the perfect midfielder, up there with Yaya Toure, who he far outshone at Wembley. Like fellow British talent Jack Wilshere, the hope for Arsenal fans will now be a full season without any major injuries, because the Welshman could be the difference between silverware and settling for fourth spot in the league.
This could give the Londoners the belief to mount a title challenge this year
Much of Arsenal's issues last year came against the sides above them. They suffered heavy defeats against the champions, as well as against Liverpool and Chelsea, results that would have almost certainly cast doubts within the dressing room as to whether they were good enough. The performance and result in the 3-0 win over the best team in the league in the Community Shield, albeit a weakened one, should have gone a long way to dismissing those concerns, and should see the Gunners approach those title deciders with much more self-belief than they displayed in 2013-14.
