This may be a hot take but I actually think we stand a better chance of winning against Real than Atletico, provided we actually advance against PSV. Atletico is basically a supercharged version of the type of team we have struggled so much against in the last two years: mid-to-low block teams that restrict the middle of the pitch and give us no room to breathe on the attack.
Real's attack is terrifying but they don't always control games and definitely give up chances on their end. They want to play a high tempo transitional game where their freelancing attackers can flourish and I feel like we can negate a lot of that with control and our excellent defensive structure and discipline.
