Return Cell Address of Number used in Minimum Function

I need to return the value of

Formula:

OFFSET(0,-1)

for the below, so that I am getting the label next to the number which provides the minimum. For example, return the lable of a number that gives me the minimum.

Formula:

{MIN(F2-LU!B3:B5)}

Any help on how to combine a match and min to accomplish this?

Thanks in advance.
