I feel like the whole "teams should focus on just one thing" was basically broken last year. City won all three major ucps and that should show you that not all teams have that trouble. I understand that some teams may barely win one, most teams win none, so this is basically a defensive statement regards to those teams, like Arsenal being able to win premier league would be more than enough, they do not need anything else. But if you are a team like Bayern, City, Madrid then these three could win multiple a year, or they could just win none but they don't have to focus on just one of them.
