United host Everton today.
"The key thing is that we have to win against Everton in order to even give ourselves that chance," Ferdinand told the United Review.
"All we're thinking about at the moment is that game, not what we can or can't do next weekend or the weekend after that. And Everton always give us a tough game so we need to make sure we do the job properly.
"Nikica Jelavic has come in and grabbed a few goals - he looks handy - and they're the sort of side who give their all for the manager."
