MANCHESTER, England (AFP) -- Ryan Giggs has told his Treble-chasing Manchester United teammates to write their place in history as Sir Alex Ferguson's side return to Premiership action.

Having booked a semifinal Champions League date with AC Milan and a place in the FA Cup final, United look to extend their lead at the top of the table when Sheffield United visit Old Trafford today.

Victory will give Ferguson's team a six point lead over second-placed Chelsea, who face London rivals West Ham 24 hours later at Upton Park.

And Giggs, a member of the United side which last won the Treble in 1999, believes the current side are well placed to repeat the historic feat of eight years ago.

"With the momentum we are building this team are capable of winning the treble. We need to carry on winning and that will build the confidence even more," said the Wales winger.

"The history books show the team of 1999 won the Treble. This team has the ability, but we still have to go out and win the trophies. "It's a hell of a month coming up. The games are coming thick and fast. "But we can put the FA Cup to bed until the final and concentrate on the Premiership and Champions League."

Having sentenced Roma to a seven-goal Champions League thrashing last Tuesday before beating Watford 4-1 on Saturday to reach the FA Cup final for the 18th time, Sheffield United should present few problems for Ferguson's rampant side.

The Yorkshire club have not won at Old Trafford for 34 years, although they arrive at the venue in high spirits having secured a crucial 3-0 win over fellow strugglers West Ham on Saturday.

That has given Neil Warnock's side hope of avoiding relegation in their first season back in the top-flighted a three-match losing run.

"I don't think there was anything significant in the result other than we showed we are still very much in it after people had written us off over the last few weeks. "I think the media have presumed both West Ham and Charlton would finish above us. But we have brought other teams into it now, which we wanted to do, and I don't think anybody can say who is safe and who is not."

United are likely to be without Rio Ferdinand. The 28-year-old England defender limped out of the FA Cup semifinal with a groin strain, joining Gary Neville, Nemanja Vidic, John O'Shea and Mikael Silvestre on the injured list.

Ferdinand is confident the injury is not too serious and hopes to be back in action as early as Saturday when Middlesbrough visit Old Trafford.

"I should be all right for Saturday but don't know about against Sheffield United," said Ferdinand.

Neville may be fit to face AC Milan in the Champions League on April 24. The United skipper has been missing since suffering an ankle injury in the win against Bolton in March.

"Gary has a slight chance for the Middlesbrough game but a good chance for the AC Milan game," said Ferguson.

Ferdinand's injury against Watford on Saturday meant midfielder Darren Fletcher was deployed as a makeshift right-back, with left-back Gabriel Heinze partnering Wes Brown in the center.

Ferguson could be forced to field the same back four today or he could be tempted to give 18-year-old FA Youth Cup star Craig Cathcart his debut.
