Bolton go to Stoke City needing victory to be sure of being safe.
"Stoke will want to finish the season on a high, I've known Tony Pulis since I was 16," Megson said.
"He will not want to sign off on a defeat. He's an honest guy and will want to get the job done on Sunday.
"It's looking desperate for Bolton but it's all in their hands. If they do manage to do it, they will certainly have earned it."
