You can decide a course you will go and do this, first like 10 yards fast small steps, then slide to the left/right, fast steps again, slide the other way, small steps then sprint 100% as long as you like.
I did this a couple of times a day 3 days a week last summer and it improved my footwork,speed and defence

goodluck!
BTW; After you've done it IF you're at a basketball hoop/court shoot 10 free throws

will make it game like since you're tired !
