A Will Hoare goal five minutes before half-time was enough for Crystal Palace's under 18 side to beat Leeds United and secure their first victory of the season.
Ken Gillard's youngsters had to put in a tough, dogged performance against their opponents and scrapped hard to collect a deserved three points - ensuring they have a win, draw and loss from their opening three matches.
Palace enjoyed the better of the first half and Elliot List went close with a snapshot before Corie Andrews linked up well with Kiye Martin on the edge of the area and forced the Leeds goalkeeper into a smart save.
On his comeback from injury, Jacob Berkley-Agyepong then went close after going through on goal and attempted to lob the goalkeeper but it just dipped over the crossbar.
However the game's key moment came on 40 minutes when Andrews broke through on goal and went one-on-one with the goalkeeper, but a defender came back to trip the Eagles striker from behind and concede a spot-kick.
Hoare stepped up to take the penalty, and despite seeing his initial attempt from 12 yards stopped he tucked home the rebound to put the visitors ahead before half-time.
At the interval the hosts made a few alterations and caused the Eagles many more problems than in the opening 45 minutes, but found Bradley Comins in inspired form. Firstly the Palace shot-stopper saved an effort from point-blank range by getting down low to parry away, and then displayed real bravery by charging out of his area to dive at the feet of an on-rushing attacker to prevent him from equalising.
At the other end, Michael Phillips went close with a header from a corner and Berkley Agyepong also had another opportunity, but there was to be final minute drama when the referee controversially penalised Palace for a contentious backpass, however the free-kick from inside the area was blocked and scrambled away as the visitors returned to south London with their clean sheet in tact.
