need more opinions

okay so this is a CL situation. I played a team and won first leg 0-5(away) they played 4-3-2-1 dl-dc-dc-dr ml-mc-mr aml-amr st. Then i played them earlier today i was home this time and got waxed 1-5... My team out qualities this team by 2 points. However this time they played a 5- 3- 1- 1 dl-dc-dc-dc-dc ml-mc-mr amr st. Anyone else have some thoughts as to what happened? Right now i play two squads, one for league one for cup and CL. The only thing i can think of is that in my cup game yesterday i won 11-3, maybe my squad was hung over? Idk. I'm only in my 2nd season so i was looking for more thoughts. (already reached out to one person and got their thoughts)

Try in some games (even if you have better quality) defense mentality, with counter attacks.

I always use defensive strat.
