Hello, I am currently using 3-4-3 for my team and doing great, I'm currently a level 2 manager.

Should I change my 3-4-3 formation ( classic ) for this ?


Even if I am pretty happy with my performances, I think I may need to change it because 3-4-3 will not work anymore on higher levels.

Please tell me your opinion, which formation I should choose and why.

Thanks.
