Youngers on form as Gunners destroy champions of Portugal.
Arsenal have one hand on the 2014 Emirates Cup trophy after hamming Europa League finalists Benfica 5-1 in North London.
Yaya Sanogo scored four times, sandwiching his goals around a debut strike from Costa Rica forward Joel Campbell.
At the other end, Arsene Wenger’s young defence, including teenagers Calum Chambers and Hector Bellerin, coped very well with the occasion. A Nicolas Gaitan goal from a long throw-in was the only blot on their copybook.
Here’s how the players rated:
Goalkeeper: Damian Martinez – 7
The Argentine stopper was a commanding presence behind an inexperienced backline. He made good saves to deny Salvio and Bebe.
