Comparing two columns of text

Hello Excel community!
Thank you so much for clicking on my question - I have found this site to be very helpful and informative.
On the attached, you will find four columns of text data. Columns A:B are from one system, and columns D:E are from a different system. I need a quick way to compare the data in columns A:B to the data in column D:E. and then compare the data D:E to A:B.

As you can see, columns A and D are Sales Managers and columns B and E are Sales Reps. I need to be able to specifically "call out" or identify where I have discrepancies between the two.
Can someone help me with a quick and intuitive approach? Thanks!

thank you so much for your help!
Unfortunately, I'm looking for a more intuitive approach rather than a concatenate and vlookup as this causes many N/A returned.
for instance, if you look at Lorabi, Boubakeur who reports to Accomazzo, David. In your solution, it shows no match; however, if you just look at the data, there is a match between
the two columns although it is not a perfect text match as one column has Mr. in front and the other does not.

Is there a more intuitive solution?
