Manchester United boss Sir Alex Ferguson believes that Chelsea have benefited from easy draws in their past FA Cup campaigns.
The Blues have won the cup four times in the past six years, including last season's triumph over Liverpool.
"They have a good record, but we try to win it every year," he told reporters. "The last few seasons we've had some very difficult draws.
"I think Chelsea have enjoyed the benefit of home draws over the past few years and I don't think they have had one hard game in their run to semi-finals over the years."
United take on Chelsea in their FA Cup quarter-final replay at Stamford Bridge later today.
