An excellent team display saw a youthful reserve side triumph over an Arsenal side boasting several players with first-team experience.
Ashley Miller scored the only goal of the game with 18 minutes remaining when he pounced on a rebound after Arsenal goalkeeper James Shea could only parry Christian Montano's shot. A dogged defensive showing saw out the remaining time to leave West Ham celebrating a Barclays Reserve League South double over the Gunners following the 1-0 win back in October.
"It was great result and the boys were brilliant and worked hard and put in a good performance," Dyer said. "I know some people thought that before we came here that we wouldn't stand a chance because we were very young but they were very young as well. But it is still Arsenal and they are in the FA Youth Cup quarter-final. It was great win and the boys are chuffed with it."
17-year-old winger Danny Kearns had almost given the Hammers the lead at the end of the first half when he fired against the underside of the crossbar after a jinking run, while goalkeeper Marek Stech also played a key role by making several crucial saves.
At the back, captain Bondz 'Gala, who like Stech has featured on the bench for the first team this season, played alongside 18-year-old Icelandic youth international Holmar Eyjolfsson in central defence. The pair, along with full-backs Miller and Matt Fry, both received particular praise from Dyer after the game.
"The defenders were brilliant. Bondz has worked hard over the weekend and he put in a great performance. It was Holmar's first game back from injury and he was great as well. Ashley Miller showed some great character on the right and on the other side we had Matt Fry, who has played centre half for the reserves and has played centre half for the youth team and was quality at left-back.
"Overall the back for were outstanding so the midfield boys could go on and express themselves, which they did do."
