Despite taking a first minute lead, Blues U18s were comfortably beaten by Brighton.
George McGee (pictured) fired Blues in front after chasing down a back=pass and dispossessing the goalkeeper, before slotting the ball home.
But the young Seagulls struck back with an equaliser just before the half-time break and then sealed the victory with a 75th minute goal.
Academy coach Steve Spooner admitted that his side fell well-below the standards that were expected of them and said the margin of the loss could have been much greater had Brighton converted their chances.
"After taking the lead so early I though that might be the start of a good performance," said Spooner.
"Ten minutes later we had a wonderful opportunity to make it 2-0, which we didn't convert, and that was probably the last thing we were positive about.
"We lacked physical and mental energy, we didn't pass the ball sharply and we looked devoid of ideas. We deservedly lost the game, but hopefully it was just a one off."
Spooner felt that only two of his players emerged from the game with credit - goalkeeper Connel Trueman and 14-year-old centre-half Josh Martin
"The only positives were a couple of individual performances," added Spooner.
"Josh Martin played ever so well and some of Connel Trueman's handling from crosses was excellent."
Blues U18s: Trueman, Bernard, Moseley, Webb (O'Keefe, 72), Martin, Harding, Dunbar, Truslove, McGee, McFarlane, O'Neill.
