In my last match I had more than 10% in condition difference, 5% home advantage, and 5 average quality difference, yet I had a tie

How is this possible?

Lucky enough you didn't lose.. Played defend in an already defensive formation. Maybe kob use to reward players playing defensive and ending up creating more chance and scoring up to 4 in matches. To be realistic, manager who play defensive game in formation like 541 lack confidence in winning the match against the opponent and best they hoped for is draw which you got:) 

You play defensive vs a weaker opponent. 4 shots saved. Logical 0-0.

Not to mention  that a hard counter to overloaded defensive formation like 5 def lineup is 352. 

yes and also the player Arkadiusz Stępień who made 10 tackles, good player

Okay, what should have I done? Play in attacking mode?

If you think you will win yes.

Thanks all

Maybe your player didn't know how to play....hahahaha

After many changes, I found my own style for the team.
There is no best way to play. Experiment and find your own way.
Be bold in using players in rotation. An AvQ 45 player is completely capable of scoring in an AvQ > 50 match. The performance of each player is different in each match, I think that is a hidden point.

I understand
