Leeds United head coach Daniel Farke said Illan Meslier was almost in tears after the goalkeeper's glaring mistake cost his side victory away to Sunderland.
In the 97th minute of Friday's match, with the minimum six minutes of added time already up, Meslier allowed Alan Browne's hopeful ball into the box to squirm past him and hand the Black Cats a 2-2 draw.
A win would have taken Leeds level on points with leaders Sunderland at the top of the Championship, but instead they remain three points behind in third.
"After such a situation, you don't need to talk to Illan, he is the saddest person in the dressing room, he's more or less in tears," said Farke.
