Table-toppers Brentford edged out Palace's academy side by a single goal in their latest U18 Professional Development League 2 encounter at Beckenham.
The game's key moment came on 19 minutes when Bees winger Jeremiah Kamanzi neatly lifted the ball over Bradley Comins in the Palace goal, and despite the away side enjoying plenty of chances, Palace remained in the game until the end but just couldn't find the elusive goal to snatch a point.
The visitors enjoyed the better of the opening exchanges and after Comins had saved a deflected free-kick from Zain Westbrooke and James Ferry dragged a shot wide, Brentford netted what proved to be the game's only goal. Gradi Milenge's through-ball was controlled well by Kamanzi and showed great skill to lob the ball over Comins and hand his side the lead.
Only a great challenge by Jason Akiotu prevented Rodrigues Alves from doubling the lead before Palace enjoyed their first attacking chance when Bees goalkeeper Nik Tzanev had to produce a great reaction stop to deny Elliott List.
Brentford were showing why they were top of the table and Comins was kept busy throughout the encounter, saving well from Audrius Laucys and Bradley Clayton either side of half-time, but being just a goal behind Palace were right in the game and they nearly capitalised on a poor backpass which allowed Aaron Bissaka a one-on-one opportunity but Tzanev saved well with his legs.
Comins continued to produce heroics in the Eagles goal as he pushed away a stinging shot by Courtney Senior and Alves was guilty of missing the target on more than one occasion as Brentford looked to wrap the game up.
Ferry was next to be frustrated as Comins got down low to push his effort away and after that had been dealt with Senior headed over the top from eight yards out, but despite their efforts Palace just couldn't find the single goal they needed.
