Liverpool won the Champions League last season, a feat Ferdinand achieved with United in 2008.
But in the same period, Manchester United reeled off a host of title triumphs – three in a row between 2006 and 2009.
Jurgen Klopp’s side now look set to lift the Premier League trophy for the first in 30 years having gone 13 points clear of the EPL table.
Ferdinand believes the Reds must win then defend the Premier League before they can be compared to his crop of United greats
During a question and answer session on Twitter, Ferdinand was asked how he would compare this Liverpool team with the United Champions League winning team in 2008.
He replied, “Need to win back to back league titles before being compared but there’s no denying they’re on route to being great team!”
