Using DATEDIFF works as well, however a bit hacky since it doesn't care about datefirst:

set datefirst 1; -- set monday as first day of week
declare @Now datetime = '2020-09-28 11:00';


select * 
into #Temp
from
(select 1 as Nbr, '2020-09-22 10:00' as Created
union
select 2 as Nbr, '2020-09-25 10:00' as Created
union
select 2 as Nbr, '2020-09-28 10:00' as Created) t


select * from #Temp where DATEDIFF(ww, dateadd(dd, -@@datefirst, Created), dateadd(dd, -@@datefirst, @Now)) = 0 -- returns 1 result
select * from #Temp where DATEDIFF(ww, dateadd(dd, -@@datefirst, Created), dateadd(dd, -@@datefirst, @Now)) = 1 -- returns 2 results


drop table #Temp
