With the game ticking into five minutes of added time, Hughes’ firm low strike deflected narrowly wide, and the subsequent corner kick triggered a goalmouth scramble, but the ball simply would not fall to a red and blue shirt.
In the final seconds, another ball into the box was chested down by Sarr, who struck a fierce effort goalwards, only for Dúbravka to spring up high and push it away.
Try as they might, the Eagles simply could not find the equaliser their general dominance deserved – a madcap spell at the end of the first-half proving costly in extending Palace’s lengthy winless run at Selhurst Park.
