Ferdinand spent seven years in total at Upton Park before completing a then record £18million move to Leeds - another club he hopes will return to the top flight in 2012.
"West Ham was the team I grew up in as a kid and to see them relegated out of the Premier League was disappointing," he told MUTV.
"It was always nice to go back and play against them and see old faces and old friends but this is football and things change, things happen.
"My other old team Leeds are in the Championship now as well so times change. I just hope they come back up again next season."
