Best formation for my Squad

Hi, Hope someone can help and advise me what they think my best formation would be for the current squad I have. I have had a lot of success with the 4-2-2-2 (14 League wins, 7 runners up 4 CL and 2 Cups), but the last 3 seasons I have finished 6th, 7th and last season 11th.
