Manchester United manager Sir Alex Ferguson claims his side's task of winning the treble will be more tough than it was in 1999.
The Scot inspired his team to Premier League, FA Cup and Champions League victories in the same season 12 years ago, and with United still in contention in the same three competitions, talk of a repeat is rife.
However, with several injuries, especially in defence Ferguson is downbeat about his side's chances of repeating that historic feat.
"We must have a chance [of winning the Treble] but it’s a very difficult one," he said.
"Going away from the greed of winning three trophies, if you can win one a year you have to be happy with that. If it turns out we win only one of those big trophies, I’ll be delighted.
"I think it’s more difficult than it was in 1999. Back then we went through the last three months of the season without an injury.
"It’s amazing, that kind of luck, because at the moment we have so many injuries to defenders.
"But there’s a great desire to do it [the treble]. Anyone given the opportunity to achieve that target would try to go for it.
"I’m happy with the character of players. They never give in, no matter the score. You always think Manchester United are going to score in the last minute, which is a fantastic advantage to have."
United continue their tilt at the treble with a trip to West Ham United this weekend, before visiting Chelsea in the Champions League on Wednesday.
