Oliver Scarles admitted his West Ham debut was 'surreal' after the 16-year-old stole the show in a 3-0 win over Romanian side FCSB in Bucharest.
Two goals from Pablo Fornals and a deflected effort from another teenage debutant, Divin Mubama, ensured the Hammers - already through to the last 16 of the Europa Conference League - became the first team in the competition to win all six of their group-stage matches.
Manager David Moyes was able to give 14 senior players, including Declan Rice, Jarrod Bowen, Kurt Zouma and Michail Antonio, the night off.
