Ridgewell was relegated with Birmingham City last season and pinpointed the qualities in the Baggies squad that is likely to see them beat the drop.
He said: "The biggest factors are not losing your head and staying together as a team and just trying to graft out as many results as you can.
"You look at all the teams and everywhere is a difficult place to go and you think, 'where are the results going to come from?'
"But the main thing is to keep the team together and fight as much as you can.
"If you keep doing that, and still go down, you've got to give a nod to the other teams."
