High reps vs Low reps

 This one is very small

The difference between the two is 

Low reps with heavy weight: Is more focusing on how much power you can exert in that short period of time. so this would work on things like Jumping, sprinting, acceleration and change of direction

High reps with low weight or more: This works focuses keeping your body under that tension for a longer period of time. So it will help in stuff like ability to perform for 90 min and less fatigue in muscles (heavy legs feeling).  

Which one is better for football workouts? Mixing both of them is the best because you first work on getting maximum power and then you can slowly work on maintaining that pressure and pain for a longer period of time.

That's it
