A West Ham side including six homegrown players were narrowly beaten 1-0 by Dinamo Zagreb in their dead rubber final Europa League group game at the London Stadium
David Moyes took the opportunity to rest most of his first-team squad having already sealed top spot in Group H ahead of the Croatians' visit, and his young charges, three of whom were making their full debuts for the club, were far from outclassed, and they posed for a photograph together in front of the tunnel at the end of a historic night for the Hammers - and were tipped to "become first-team players" in the future by the manager
Moyes would have feared for their confidence when Mislav Orsic, whose hat-trick knocked Spurs out of the competition last season, struck another sensational strike from distance with less than three minutes on the clock, but the home side regained their composure and held their own against their far more experienced visitors
Full-backs Harrison Ashby and Emmanuel Longelo in particular impressed, and the former carved out West Ham's best opportunity of a game of few chances, finding Sonny Perkins with a pinpoint cross which he nodded over from a good position
The defeat, West Ham's first in Europe this season, could not stop them from finishing top in Group H, while Dinamo did enough to ensure they qualify for the play-off round by finishing second, although Genk's defeat to Rapid Vienna meant any result would have been enough for the Croatians to progress
With their progression already assured, West Ham's team-sheet showed the result was secondary for David Moyes in their final Europa League group game with six homegrown players, including captain Mark Noble, named in his starting line-up
Ironically it was two of his older charges, Andriy Yarmolenko and Pablo Fornals, whose half-hearted pressing allowed Orsic space for his opener, although few would have expected him to beat Alphonse Areola from the corner of the penalty area, with his strike off the far stanchion a stunning goal
Once the young hosts regained their composure they should have levelled
 Perkins did everything right to meet Ashby's excellent cross from the right but his header let down his good preparation, and he nodded harmlessly wide from an inviting position
The visitors nearly made West Ham pay as Daniel Stefulj drifted past Ashby out wide with ease and picked out Arijan Ademi unmarked in the middle, where he too fluffed his lines and nodded harmlessly over
The second half offered little as a spectacle at either end with Dinamo's one-goal lead enough to see them through, while the Hammers huffed and puffed without building any serious momentum
Orsic was denied a second by a wayward shot which bent just the wrong side of Areola's goal frame in the only real chance of note, although the Hammers came close to a late equaliser out of nothing from an unlikely source, as centre-back Aji Alese stretched to meet Alex Kral's flick but was just beaten to the ball by goalkeeper Dominik Livakovic
West Ham manager : "I thought they did really well
 We scored a fluke against Chelsea from the same area but apart from that, I thought the young boys did really well
"It was a tough game, ideally we would not play five [young players] but we were forced into it slightly
 Overall, I thought they all acquitted themselves well
 At times you could see their youthfulness - but you also saw some of them out there will continue to improve and become first-team players
"I am always happy to give young players a chance, but I have to be a realist and say they must earn the right to play
 None of them let us down, they did a great job - but I also would like to be in a situation where I do not have so many on the pitch at one time
