United are currently top of the Premier League, booked their place in the FA Cup semi-finals on Sunday with victory over Arsenal and face Marseille in the Champions League last 16 on Tuesday but Ferguson warned his players they need to improve.
“The team needs to step up a level,” he said.
“It’s an important time, being involved in three tournaments. The key is to have everyone available. It would be nice to get that.
“It doesn’t matter how many players you have had injured in the past, the important thing is to have them all available for the run-in. If we have that, then it will increase our chances of success.”
United have lost their last two Premier League matches, something which frustrated their manager and he revealed he expects much more from his side if they want to match the treble winning team of 1999.
“They need to perform if they want to win the Premier League and stay on course for the Treble,” he concluded.
