usually I follow my assistant coach advices if I do now know the opponent players well
obviously if I play against Manchester City or PSG, Haaland and Mbappe are the ones to focus on with tight marking pressing.
Another thing to take into consideration is the use of " force to play on weaker foot": if the opponent player has both feet equally strong (you can check on his profile) this OI is not only useless but also damages your tactic balance
