Convert Mysql Query to Laravel 5 Eloquent

I am using Laravel 5.1 in my application. My MySQL Query is

$result = DB::select(DB::raw("Select * from "
            . "(Select u.* from "
            . "( "
            . "SELECT u2.id as user_id, u2.fname as fname, u2.lname as lname, u2.uname as uname, u2.email as email, u2.address as address, u2.city_id as city_id, u2.website as website FROM users u1, users u2 where u1.city_id = u2.city_id && u1.id = '$this->current_user_id' ) 
                u left join follows f on u.user_id = f.following_id where f.following_id is null 
                UNION
                Select uu.id as user_id, uu.fname as fname, uu.lname as lname, uu.uname as uname, uu.email as email, uu.address as address, uu.city_id as city_id, uu.website as website from users uu where uu.id in (Select u.user_id from (SELECT user_id FROM reviews group by user_id order by count(user_id) desc5
                ) u left join follows f on u.user_id=f.following_id where f.following_id is null
                )
                ) 
                T LIMIT 5"
    ));

How Can I convert it in Laravel Eloquent?
