The Jacks manager replaced goalscorer Wilfried Bony as well as Roland Lamah and Nathan Dyer all after the hour-mark at the Kuban Stadium as his side again conceded an injury-time equaliser to the Russians.
After the match, Laudrup explained his reasons for bringing two of the trio - who were the team's best players on the night - to the bench at such a vital stage of the contest.
"Roland has not been playing a lot so it's normal. He gave a lot, he was fantastic in the first 45 minutes and it's normal after an hour he would be tired," said Laudrup.
"Nathan is one of the players that has played the most this season and at that time I thought too many times we ended up with four up front and too much work for our two midfielders, so I wanted to strengthen that area."
