For the second game in succession Palace's development side overturned an early deficit to pick up a 2-1 victory, with goals from Osman Sow and Jerome Williams helping Gary Issott's side beat local rivals Millwall.
The Eagles made the short trip to the Lions' training ground having won their last away outing at Ipswich Town, but made a poor start and found themselves a goal down in the opening couple of minutes when some slack defending saw a home attacker burst through on goal and tuck the ball past Lewis Price.
Despite the early setback Palace fought back and after Conor Dymond won the ball in midfield he released Jerome Williams, and the left midfielder burst through on goal to force the Lions keeper into a good save.
However parity was restored on 20 minutes. Williams terrorised the right back to get to the byline and pulled the ball back for Osman Sow to poke the ball home and register his first Eagles goal since arriving in the summer and level things at at one each.
Late in the first half the hosts nearly regained their advantage when a flowing move down the right led to the ball being pulled back to a Millwall midfielder who blasted towards the top corner but Price was at his best to push the ball away before Alex Wynter blocked the rebound to keep things even at the break.
For the second game in succession though the Eagles came from behind when they took the lead on the hour mark. Reise Allassani slid the ball into the box for triallist Ayo Obileye to lay off to Williams whose shot on the turn found the net to turn the game around.
Millwall threatened little in the second half but did cause one moment of panic when a cross from the left was deflected into the path of an on-rushing striker who saw his controlled volley smack against Price's post before deflecting out of play.
Indeed the final chances of the game both fell to Allassani. Firstly the winger cut in from the right and let fly with an ambitious effort that narrowly flew over the crossbar, and then in the dying stages he continued to torment the home defence by wriggling past three defenders before getting a shot off which had to be pushed over, as the Eagles collected a second straight victory.
