well its a cup game, 90 to 80 is not a big gap either so tactic does matter, well my team always going that rought time in a cup and champ, same tactic that i used to destroy in a league (or cup / cl early rounds) but seem harder when it comes to a cl or cup (especially when its a quarter or semis or even final match), better set bonus high if you not confident enough! , losing money better than losing chance
