The chances kept coming: seconds after that intervention, Mathurin led yet another counter-attack and slipped in Umeh down the inside-left channel. Bearing down on goal, the forward’s placed effort was well-stuck – but agonisingly hit the inside of the post before bouncing away.
As the clock ticked into stoppage time, Whitworth came to the rescue again, springing high to his left to keep out Amadou-David Sanyang’s effort across goal as both sides finished strongly.
There would be one final chance for Umeh in the third added minute as he weaved between two defenders, but on this occasion he could not reproduce his last-gasp heroics of the weekend.
A red-hot finish to a match played in bitterly cold conditions – but most importantly, a draw which sees Palace guarantee their progression to the next round, unbeaten in four group-stage matches.
