In what was a tightly-contested fixture, Thomas Frank's side should've had a penalty after Palace centre-back Marc Guéhi clearly handled in the area, but referee Simon Hooper flagged an apparent foul by Christian Nørgaard.
Despite failing to grasp the opportunity to leapfrog their guests in the table, Brentford defended brilliantly and kept their first clean sheet in 14 matches (all competitions), the last coming in their 1-0 win against Everton on November 28.
Speaking to the club's media after the match, David Raya expressed his happiness with the team's defensive unity.
"I think defensively, the last two games especially, we have been very solid, [we] gave them nothing. The lads were brilliant from the top to the bottom of the defence. [I am] happy with the defensive performance."
It was the 26-year-old's first game back in front of the home fans after making his comeback from injury in trips to Everton and Manchester City. He's pleased to be back but admits he doesn't feel entirely himself just yet.
"It's coming along. Obviously, three games after nearly four months out is not enough, but that will come along during the next few games.
"Hopefully I will feel back to my normal self. I don't feel back yet but it's coming along nicely. It's nice to be out here with the home fans and the performance defensively was really good so I am very pleased to be back."
The Spaniard now has 36 league clean sheets to his name since his arrival from Blackburn Rovers in 2019, which is the third most for any Brentford goalkeeper in the top two divisions - the record being 51.
When informed of the achievement, Raya showed humility by attributing to the defensive effort from the rest of his team-mates.
"It feels good. It's not just me, like I've always said, it's part of the foundation we have defensively. We defend from the top and we finish on me, so that's not just my reward, it's the whole team's".
