And the reason, according to Ferguson, lies in a surface he says has simply "collapsed".
"The pitches over the last few weeks have not suited Darren," Ferguson said. "They are really heavy pitches. Unfortunately, Old Trafford seems to have collapsed in the last two weeks.
"We have had six great years out of the pitch. Our groundsman, Tony Sinclair, has done a fantastic job. But it is looking tired now and I think we will have a new pitch in the summer."
