Who wants help choosing the best formation and tactics based on these players?

[Carlitos]

Hello guys,
I'm going to post my players because I'm not anymore happy with my results.
I'm posting the full team and also pics of average offensive/defensive/menta/fisical stats.
I'm LVL2 I will play league and CL, so feel free to suggest me who to sell and who buy.
Right now i feel I've spent too much and I don't know which formation i should use.
Thanks in advance.
The pics are in this order:
The team (start SA position )
Age / value
average attack stats
average def
average ment/fis
Again thanks in advance.
