How to land a sports plane with tailwind?
Land normally.  Check your POH (Pilot Operating Handbook) first to ensure you have enough runway including the extra needed for a tailwind.  The only thing to watch out for is that winds tend to moderate as you get closer to the ground.  In a headwind landing, the relative wind will decrease, In a tailwind landing the relative wind will increase, so there will be an increased tendency to float way down the runway.  Be on speed for a short field landing technique.
