Gary Neville is relishing the challenge of fighting on three fronts as United prepare to enter the final month of the campaign.
The Reds' skipper, who has been out of action with an ankle injury for the last four weeks, says the team's progress so far this season is already an achievement to be proud of. But he insists the players are determined to ensure they end the campaign on a high.
"It is a great prospect for all our players knowing we are going into the last month of the season still going for the three major trophies," Neville told Sky Sports News.
"It is where we wanted to be for the last three seasons and now we are here, we are going to enjoy it.
"There are similarities (to 1999) as we are still in the three competitions and it is tremendous achievement to be in the three competitions at this stage, not just for ourselves but for Chelsea as well.
"But there is a long way to go and we haven't won anything yet, we don't have any medals round our necks yet.
"The hardest work is still to come," warns the 32-year-old. "There has been a lot of work done by both teams in the first ten months of the season and this last month is the all-important one.
"Whoever wins those crucial moments in the matches will go on and finish the season the happiest."
Neville could be back for United's Champions League semi-final first leg at Old Trafford on Tuesday.
