Of the 2-1 victory for the younger side, Peter Brabrook said: "It was a pleasing performance and we could have scored six."
They were happy to settle for two, though, scored by Brent Tattam and Graeme Carrick.
A 2-0 loss for the under-19s left Tony Carr extremely disappointed, and he said: "They were better than us but not great.
"It was a very poor performance and there are no excuses; it was the worst performance of the season.
"It was disjointed, mistake-ridden, and lacklustre.
"I am choked because we worked hard all week only to produce a performance that wasn't worthy of the West Ham shirt."
Of the two goals in the 2-0 defeat, Tony said: "The first was a howler from the goalkeeper who missed an innocuous cross - it was a horrendous mistake.
"We rallied a bit in the second half but a poor clearance from the keeper led to a penalty being conceded by Metitri."
