How to implement a high defensive line and tight marking

[Jimmy_x_]

I am playing a high defensive line with the offside trap on and pressing. My two full backs are on support duty, whilst my centre backs have a defend duty ( central defender and ball playing defender). How would you advise i use tight marking here? Should the full backs have tight marking and the cb's without, or should they all not have tight marking? please help if you can

thanks
