United's title defence has suffered a serious setback with two defeats in their last two games. They are still a point ahead of Liverpool with a game in hand, and Ferdinand said they cannot afford any more slip-ups in their remaining fixtures.
Ferdinand said: "We need win all the games that we have left - that's always the case at this stage of the season.
"There's no time for saying we can draw this one or that one - that's not the game we are in at the minute.
"We have gained some great experience over the last couple of seasons that at this stage it comes down to winning at all costs, so hopefully we can lean on the experience that we have gained."
