Compare selected Client with TOP N Clients excluding the selected Client based on Volume

[Anonymous]

I am new to Power BI. I have a requirement to compare selected client with TOP N clients based on volume excluding the selected client. The Client Slicer (dropdown slicer) is where the client is selected to compare with the Top N clients. For example, the image below: 

If I selected Client E on my Client Slicer and comparing E with Top 3, then I want to achieve report below:

However, if I selected Client E to compare with Top 4, my result should look like

Note that since i selected E, it will be excluded from the Top N returns.

I will appreciate any help.

Thanks for solution. However, I want to ask that when the visual is Matrix the Selected Client won't appear at the top. How can I go about the selected client appearing at the top when using Matrix visual?

Thanks parry2k. I thought it is not possible but i thought wrong. This is awesome.

@Anonymous ,  Prefer to create a client table disconnected

A new measure for volume

Vol= calculate(sum(Table[volumne]), filter(Table, not Table[Client] in values(client[client])))

Try TOP N like, Use a what-if to change 10

Top N Rank = CALCULATE([Vol],TOPN(10,allselected(Table[Client]),[Vol],DESC),VALUES(Table[Client]))

Top N Rank = CALCULATE([Vol],TOPN(10,filter(allselected(Table[Client]), not Table[Client] in values(client[client])),[Vol],DESC),VALUES(Table[Client]))
