SQL Select - Distinct - Random

these are fields of my table table1 (position, club, country, flag) and

and I need to show randomly club name without repeating the country,

a use this query

select top 4 position 
from table1 where flag = 0 
and exists(select distinct country from table1) order by newid()

but turns out to repeat the name of the country,

can you help me?

thank you,
