In the 1st leg match, it seemed that your opponent attacked on the middle with his best MC as key player, and your 2 MCs failed to stop his best MC. Therefore, you will want to control the midfield with 5 players in the 2nd leg. Furthermore, I noted that your opponent's DR and DL were not very good in battle against your wingers. I think 3-5-2 flat with red arrows on your MR and ML would work.
