Display Users and user url's in wordpress

I need some help I have the iteration working for listing the wordpress users however I also want to wrap their names in links and can't seem to get the user url to work... Nothing is returned to me.

Here is what I have so far.... You will see that I am trying to pull in the user_url however it just returns as nothing. Any help would be great! Thanks

<?php
  $blogusers = get_users( 
    array( 
     'role' => 'subscriber',
     'fields' => 'all' 
  ) 
);

echo '<ul>'; 
foreach ( $blogusers as $user ) {
   echo '<li><a href="' . $user->user_url  . '">' . $user->display_name . '</a>';
}
echo '</ul>'
?>
