you will have about 6 minutes between the end of game 1 and the start of game 2. But only 3 minutes to make the subs. So, only spend a few seconds looking at the post match stats. Then go right to making your subs. Have things planned out before hand so you know what formation and which players are playing. You may want to boost morale before game 1, though it could drop if they don't play in game one. But, you should have enough time to change their morale too. And to apply the skill points. I've done this before and have been successful.
