No clue how i lost this match up?

Ok, so I’m a new player and I’m still working a lot of this all out.
Second league season now so I’m getting there.

However I just had a champs league match up that I lost 0-1 and I have no clue how.
The match up %s were 58% (26.9) - 87% (19.7)
I was actually watching this game live and was using the extra bonus click things.
My team was rested and had full morale.

My opponent lost their last game 9-0 against someone who was lower rated than me.

The only thing I can think of is a formation mismatch.
How much time do you put into how your team is structured for each game? Is there somewhere you can go to research common ways to counter particular set ups?
