Elliot Lee bagged four goals as the Development Squad produced a five star performance to hammer Ipswich Town 5-0 at Rush Green.
Lee got the rout started after just seven minutes with a deflected free-kick before doubling the lead with a powerful finish just before half-time.
The striker bagged his third and fourth goals within the space of two second half minutes as the home side tore their opponents apart time after time.
Pelly Ruddock completed the demolition job with 15 minutes remaining when he powered home first time to round off the perfect performance.
The Development Squad had won four of their six Barclays Under-21 Premier League matches coming into this friendly and they continued that form with another outstanding display.
The Hammers started the brighter of the two sides and could have been ahead as early as the second minute when Sean Maguire found himself in the middle of the box with plenty of time after Keiran Sadlier's pull-back but the Irishman could only fire his shot straight at the keeper.
It was not long until Nick Haycock's side found themselves in front however as the prolific Lee struck a free-kick which benefited from a lucky deflection to nestle in the back of the net having wrongfooted the visiting keeper.
Lee was a constant menace to the Ipswich defence and should have doubled his tally before he did when his shot struck the keeper and, following up on the rebound, he placed his shot just wide.
A minute later and the striker was celebrating his brace as a lightning quick counter attack saw the ball arrive at the feet of Lee who beat a man before firing past Michael Crowe in goal.
Blair Turgott was introduced at the break and should have made it 3-0 with his first touch of the game but instead blazed Maguire's cutback over the bar just two minutes into the second half.
Despite the winger's miss the Hammers third goal didn't take long to arrive as in the 57th minute Lee was once again on hand to head home after a Matthias Fanimo shot cannoned off the bar.
Incredibly the striker bagged himself a fourth just 60 seconds later when a smart turn in the box allowed him to pick out the bottom corner.
Ipswich found themselves trapped in their own half as the home side refused to take their foot off the gas as they searched for more goals.
Lee came within inches of his and his side's fifth goal but was his low curling effort struck the post.
West Ham's fifth arrived after a rare Ipswich attack was thwarted by Ruddock, who played the ball to Turgott and continued his run from inside his own half down the right wing and eventually received the ball back from Turgott to hammer a first-time shot past the helpless keeper.
The Hammers continued to press but the damage had been done and a 5-0 win represented the perfect return for their total domination.
The Development Squad are next in action when they play Norwich City Rush Green on Friday 4 October in the Barclays Under-21 Premier League.
