    Although Arsenal's crushing 5-1 victory over Benfica was only a friendly, it still offered plenty of insight into the Gunners' prospects for the 2014/15 campaign.

    Yaya Sanogo's four-goal haul will take the headlines, but there were also promising performances from several other young stars.

    Go to the next slide to discover what Arsene Wenger and the Arsenal fans can infer from this confident win.

Yaya Sanogo Can Score Goals After All

    Going into this match, Yaya Sanogo had never scored a goal in an Arsenal shirt. He ended this match with four under his belt.

    It may only have been a friendly, but those goals will have meant an enormous amount to Sanogo. As the wait for a goal went on, it must surely have begun to play on his mind and inhibit his game.

    Arsene Wenger will hope that will give him the confidence boost he needs to get off the mark in the Premier League next season.

Joel Campbell Looks the Part

    This was actually the first time that Joel Campbell pulled on an Arsenal shirt at the Emirates Stadium, despite signing for the club three summers ago. The Costa Rican had a solid debut, scoring with a well-placed volley to make an immediate impression on the Gunners crowd.

    Although Campbell still looks raw at times, and may need to work on his stamina, he appears to have the talent required to play a part in Arsenal's squad for 2014/15.

Arsenal Have Too Many Right-Backs

    Even though Arsenal have allowed Carl Jenkinson to leave the club on loan, Arsene Wenger still has a surplus of right-backs at his disposal. In addition to Mathieu Debuchy and Calum Chambers, the Gunners can also call upon young Spaniard Hector Bellerin.

    Bellerin was the game's outstanding player. His marauding runs down the right were a constant menace, and he made a tremendous impact in the final third.

    Bellerin looks ready for the rigours of first-team football. Perhaps a loan spell to another Premier League club may be in order.

Calum Chambers Is an Option at Centre-Back

    In this match, Arsenal played with two players at centre-half who are more conventionally recognised as full-backs: Calum Chambers and Nacho Monreal.

    Wenger views Chambers as a long-term option in the middle, and in this game he looked assured in what is still an unfamiliar role. With the future of Thomas Vermaelen still in doubt, Chambers' relative comfort at centre-back is a huge boost for Arsenal.

Arsenal Still Need That Elusive Holding Midfielder

    If there was one weak link in the Arsenal side, it might have been Mathieu Flamini. Although he showed his customary energy in the quarter-back role, he looked somewhat limited on the ball.

    If there is one area where Arsenal could yet improve their options, it is holding midfield. The transfer window still has a month to run, and Gunners fans will hope Arsene Wenger is still scouring the globe for potential signings.
