The Black Cats have developed a custom of snatching late goals since the Irishman took charge 16 months ago, and Keane now wants to see more of that from his side as they look to claw themselves out of the Premier League's bottom three.
"There have been certain games this season where we should have got something - West Ham away, Blackburn at home spring to mind and there was the Newcastle game here, especially," he said.
"We're aware that they are those few extra points that we might have had which would have made a difference in the table.
"So that's why we keep saying every point is vital and why we have to fight to the last. Every point is vital because you never know what you're going to get and you have to keep on going to the end to see what you might get.
"You need character to do that, to keep on battling, but our late goals have made the difference - otherwise we could have been right at the bottom."
