All the latest news, views and transfer rumours from Old Trafford…
The two sides played out a 0-0 draw on Friday and they will face each other again on Tuesday February 3 with the kick-off at 19:45 (GMT).
With Manchester City, Chelsea, Tottenham Hotspur and Southampton all crashing out of the competition over the weekend, Louis van Gaal’s side now have a great chance of winning the competition.
But they will not be taking anything for granted against a Cambridge side that gave them an almighty shock just a few days ago.
The latest report claims that van Gaal is a big fan of the German international and wants him to shore up a defence that has looked anything but secure on a number of occasions this season.
