Issues with opponents getting stronger after red cards

[Farfromtilidie]

Just had two ridiculous results in successive matches in the CL. First match was the final group game, teams fairly evenly matched. For their team see screenshot 1. At 1-0 to the away side they then get 2 red cards by 49th minute (screenshot 2), so are playing 2-4-2 with holes in CM and centre of defence. Opposition manager keeps the same formation, the final score? 2-1 to them.

Next game in CL, I'm at home and 3-1 up when in 55th minute they go down to 10 men as one of their two CB is sent off. I keep same tactics (hard attacking, press over whole pitch) and so do the opposition as the manager isn't present. The final result? 3-4 to them.

What a joke!!! Red cards make the opposition better?! WTF?!!!!
