From what I can see, assuming you've been training SF and PF, some of your players have lost maybe one minute per week. That's not worth getting too concerned over, but I would guess for example that singe it's happened twice to Nicolas Peter, his stamina may be exceptionally low. If you're winning that convincingly every match, it may well be better to just dress five players if you're that concerned about the missing minute, since game shape isn't going to matter, nor will an injury probably derail you.
