Sir Alex Ferguson insists there will be no complacency from Manchester United even though he intends on leaving a number of star names on the sidelines for the Champions League semi-final decider with Schalke.
United go into the Old Trafford encounter two goals ahead thanks to their efforts in Germany last week.
It offers Ferguson valuable breathing space given the Chelsea juggernaut will roll into town on Sunday for a game that is expected to determine the destination of the championship.
and Rio Ferdinand are amongst those who look set to miss out, but Ferguson insists his team will have their minds fully focussed on a Wembley date with Barcelona on May 28.
"It is always dangerous in football to assume you have cracked it; that you have found a sliver bullet or discovered some secret formula for success," said Ferguson.
"We live in exciting times for Manchester United and while I want both players and supporters to enjoy every minute of it, we must take nothing for granted."
