I did this to gain advantage over my opponent in the Champions League. He was also in my league so I knew what time his matches were. The first leg finished 4-4 so a draw or win at home would be enough but he was very tough to beat. I rescheduled the CL match 15 minutes after his league match, whch was also an away game for him. As he couldn't do a thing about it, he was unable to make changes and use boosters. He got an injury in the first game and I beat him 3-0.
Changing it to your advantage works, it wont make you popular in your league but it benefits you
