Manchester United skipper Rio Ferdinand is delighted with his team's current form, and wants them to continue with their brisk momentum right up until the end of the season.

The Red Devils are chasing an unprecedented 'quadruple' of Premier League, Champions League, FA Cup and League Cup, a feat never matched in England, although Celtic, of Scotland, managed such a feat in 1967, the year before United won their first European Cup.

Ferdinand has highighted the efficiency and professionalism in the current United squad, as they have overcome the adversity of a crowded fixture schedule and a long injury list to overhaul Liverpool at the top of the table in the last week.

"It is just about continuing what we have been doing. I think we have been very tight of late. We have got players who are very businesslike at the moment," Ferdiand explained to The Manchester Evening News today.

"The players want to get the job done, score goals, want to defend - and defend for our lives - and keep clean sheets.With that form, you are onto a good thing, but medals haven't been handed out yet so we are not going to get ahead of ourselves. We set ourselves a target, we have got to where we wanted to be at this stage, and we need to continue that now."

The commanding centre-back has missed 11 games this season due to a niggling back injury, allowing youngsters such as Jonny Evans to step into the breach and excel, but Rio remains confident that the injury can be managed effectively as he looks to help drive the side on to yet another successful season.

"I could have played a little bit longer at West Brom but the manager brought me off. I am fine. There are no problems," he added."I've just got to keep on top of it, keep working hard and keep doing my training, and continue to be injury free hopefully."
