Soccer training question

For my lifting volume I have read pakewi saying in the past 10 reps per session (1 lower body + 1 upper body) is enough for soccer player?

How should I structure my lifting then

Can I just do squat and an upper body lift? Will doing extra lifting work help me (like RDLs, extra upper body work)? Any thoughts? And how should I carry my sets? (like ramp up to 3 reps or something)
