West Ham United's Under-18s fell to defeat by the solitary goal at Liverpool in the Barclays Under-18 Premier League Tier One on Saturday.
Steve Potts' side started brightly at the home team's Kirkby Academy base, but went 1-0 down to Daniel Trickett-Smith's 14th minute goal.
Trickett-Smith posed the biggest threat for Liverpool from his striking role, although the Hammers did well to restrict his side to half chances in the main.
However, the Hammers also found it tough to create clear cut openings in a game mostly played out in midfield and they were unable to find an equaliser.
The Hammers looked assured in the opening stages, but fell behind to Liverpool's first opportunity in the 14th minute.
Republic of Ireland U17 international Alex O'Hanlon clipped over a cross from the left hand side towards Trickett-Smith, who had drifted into space at the far post for a simple finish.
It was another Irish youth international, Kieran Sadlier, who almost got the Hammers back on level terms ten minutes later when his free kick required a strong save from Liverpool keeper Ryan Crump.
At the other end Kristoffer Peterson rose well to head Trickett-Smith's 33rd minute towards goal but Hammers stopper Sam Baxter did well to hang on.
Baxter was then called upon to smother from Peterson after he shrugged off the challenge of Lewis Page, but Potts' men were still well in the contest as the half time whistle sounded.
Liverpool had a great chance to double their lead 11 minutes after the restart when Jordan Rossiter's defence-splitting ball picked out Harry Wilson, but Baxter stood up well to deny the half time sub.
Sadlier was looking lively for the visitors and his well-struck shot needed a save from Crump on 72 minutes after a good move involving Nathan Mavila and Thomas Gogo.
But the Hammers found it tough to break down their hosts after the interval and Liverpool saw time out to claim maximum points.
West Ham United: Baxter, Knoyle, Page, Girdlestone, Onariase, Burke (Harney), Makasi, Miles (Amoo), Boakye-Yiadom (Gogo), Sadlier, Mavila
