Reyes Cleary's decisive strike helped Albion's Under-18s defeat Manchester United in their final group game of the Premier League Cup on Saturday afternoon.
Archie Oliver took advantage of a United mistake to give Peter Gilbert's side momentum 21 minutes into the second half, before their leading talisman's left-footed finish secured the young Baggies' first win in the competition.
However, just one victory from three group-stage games mean the U18s haven't qualified for the knockout stages of the tournament.
But after bouncing back from a heavy defeat in the FA Youth Cup with a win over the young Red Devils, Albion will be looking to carry form into their next U18 Premier League game against Norwich City on Saturday, February 5 (ko 11am).
