The boss was asked to compare the merits of the pair after working with the Bayern Munich no.1 during his time at Schalke. Indeed, both Germans were in opposition to the Reds in the 2011 Champions League semi-final, when Neuer produced a memorable display for Rangnick's men.
United won 2-0 in the away leg with goals from Ryan Giggs and Wayne Rooney, inside a couple of second-half minutes, but Neuer produced a string of fine saves on the night.
Having worked with both keepers, the tactician is in an ideal position to evaluate just how good they really are.
