The midfielder says the club would be crazy to sack Allardyce when he is needed most.
"The teams at the bottom have lost their managers and, of course, all the talk is about Sam to go next," said Downing.
"But the players love playing for him. When a team are struggling, who do you go out and get? You go out and get a manager who's a motivator.
"The owners know this, they see sense. They know they have a good manager, they see the bigger picture - that when we get players back we have a decent team."
