Ferdinand returns to the Boleyn Ground tomorrow with his former club battling against the drop.
"With the players West Ham have - three England internationals in their starting eleven - it does surprise me they are where they are, very much so," he told The Journal.
"However, there is no such thing as a team too good to go down from the Premier League.
"I just hope, come the end of the season, West Ham are not in that situation again.
"I hope they do what we did three years ago when we went to Manchester United and won on the last day of the season to stay up.
"Even better, I hope they make sure they are safe before then."
