Isaac Hayden became an integral part of the under-21s side last season as he continued to impress both as a defender and as a holding midfielder. The England youth international has skippered Arsenal at all levels of the academy and signed a new contract with the club in February 2014. Versatile Isaac, who joined Arsenal from Southend United, even played 40 minutes in goal when Josh Vickers was injured during an under-18s game last season.
