I Decided To Try The Invincibles Challenge I Was Wandering Whats The Easiest League To Do It In Apart From The Following Countries Spain Portugal Holland Italy Germany England And Russia Which Could Be Very Tough To Achieve In
PSG. I'm currently undefeated with them in all competitions having only picked up away draws against Lorient and Dortmund in the CL. Also Ibra just won the Ballon d'Or for me with 36 goals in 25 appearances.
To go undefeated, you need a lot of talent, very good tactics, and basically a lot of luck. I managed to go undefeated with Barcelona in my 7th season. 34 wins, 4 draws, 0 losses. Honestly if you go into a weaker league, let's say Ukraine or Russia, you should be able to dominate by getting the right talent in. But going undefeated is honestly just going to require some luck.
