I did exactly as you suggested. Luckily, I have decent DC and MC subs so I only lost 3% in the AvQ of my first 11.
I got an early 2-0 lead but then things turned around and they got 2-2 (they didn’t attend so no change from their side). I subbed a MC who had a 5.8 rating at half time, but didn’t change any formation or tactical settings. Here’s the match result:
I won 4-3! Just like in the first league match! Thank you again for the suggestions!
