United play at Ferdinandâ€™s old club West Ham tonight with a 15-point lead over Manchester City.
He said: "Weâ€™ve got to make sure we finish the season correctly and get this title back. Weâ€™re not far off it but itâ€™s not over until itâ€™s over. We have to make sure we remain focused and apply ourselves in the right way.
"Iâ€™m not really surprised by the lead if Iâ€™m honest. When I look around the changing room I expect us to be winning games nine times out of 10.
"I believe in the squad, believe we can win games in various ways, winning ugly, playing fluent football, keeping a clean sheet.
"It would be great to win it again but until we do I donâ€™t want to talk much about it. Last season a lot of people got ahead of themselves."
