If you're comfortable modifying table values, I prefer to use Club > Presets > Improve Team Condition and click on Script and change from 10000 to 12500 - this is a safe value and you can go the whole match not needing to sub any players because they're not tired and achieve good performances and good results. It resets after the match back to the normal value of 10000.
Apply this right before match so the value is applied on the screen where it says Team Selection on the top left side and has your team lineup. Click on any of your players and apply Improve Team Conditioning (note this applies to YOUR team). Go back one again to Team Selection and proceed with the match.
