Webb is remaining calm and pragmatic if the worst-case scenario were to occur.
He told the Reading Post: "It's not a crisis, even if they went back down to the Championship - it didn't hurt them last time.
"The crowds were still reasonably good and you've still got parachute payments for one or two seasons.
"It's not nice being a yo-yo club, like West Brom, but they did it for about three years and now they're established, so it doesn't hurt.
"Reading are established now as a top-six Championship side, so even if they did go down, you're thinking they've got a chance of getting promotion the following year.
"A few years ago when they were at Elm Park, if they had gone down, they wouldn't have been going up.
"They wouldn't have got the crowds and they wouldn't have got the players because of the money situation, but now they can compete and they're getting 15,000-20,000 regulars - anything over that is a bonus.
"It's great to see Reading in the Premier League - I was there when they used to be a yo-yo club between divisions three and four with gates of 3,500."
