Team selection limits

iv 2 matches today, 16mins apart, 1st is league, 2nd is CL final against a team quite a bit better than me. So was going to play a lesser team in match one to avoid injuries/fatigue etc then quickly change it for the final we the best team. First match takes about 5 mins to run so do I have adequate time to alter the team for final or will I have to put final team on in game 1 and run the risks?

Previously I have tried to alter my team with maybe a few minutes to go to KO and get the message I cannot as game starting but cannot find anywhere what the limit to change team prior to KO?

change your schedule, i think that can make your team have a recovery

You have up until 3 minutes before kick off to change out your guys and orders etc.

in stadium banters would be nice right?
i just mope and moan most of the time because i forget i didnt switch between my team

there are a few cheeky rivals that set illegal formations, and they change back within 4 minutes. would be funny if they lagged and were still in an illegal formation

keep viewing ur schedule to prevent it
