Adam Wharton's first goal for Palace looked set to halt a five-match winless run in the Premier League for the Eagles, but Brentford dug deep to stay in the hunt for a top-six spot.

Oliver Glasner's side was awarded a sixth-minute penalty after Ismaila Sarr was brought down by Caoimhin Kelleher, with the Palace number seven dusting himself down to score from 12 yards after the spot-kick was given afterr a VAR review. 

Palace continued to dominate the opening period and almost doubled their lead through Sarr, but after he was slipped in by Yeremy Pino, his shot rattled against the crossbar. 

The visitor struck the woodwork again in the 33rd minute when Jorgen Strand Larsen let fly, and Brentford made them pay for their profligacy five minutes before half-time when Jaydee Canvot's headed clearance rebounded off Ouattara and into the net. 

But the Eagles restored their advantage seven minutes after the restart through Wharton, who saw his effort from just outside the area squirm under the grasp of Kelleher. 

Brentford struggled to create any clear-cut opportunities, but they did get themselves level in the 88th minute after Michael Kayode's long throw was flicked to the back post by Sepp van den Berg for Ouattara to nod in the equaliser.

The Bees could have even snatched all three points in the 10 additional minutes of stoppage time, but Kevin Schade wildly lashed his shot over the crossbar before Igor Thiago repeated the trick as the spoils were shared at Gtech Community Stadium.
