That’s because for tours, you play with players that gives you the highest SV. So it’s generally a different playing 11 from tour to tour. Players’ skills, abilities, adaptabilty with other players & managers affects your playing style even when everything is 99 & 100%. I only use Simeone for tours no matter what and there are times when I find my playing 11 this week isn’t as effective as my playing 11 the week before, but I persevere with it. If I use the correct manager everytime for all tours that suits my playing 11, I would find every tour easy to pass through but since I’d only use Simeone, I take the playing issues that come with that decision & soldier through it all.
