How can I have a class of 'current' be displayed for the current post

<ul id="post-list">
    <?php
        global $post,$wp_query;
    $current_id = $wp_query->get_queried_object_id();
    $args = array('category_name'=>company,'numberposts' => -1);
    $myposts = get_posts( $args );
        foreach( $myposts as $post ) :  setup_postdata($post); ?>
            <li<?php if ($current_id == $post->ID) echo ' class="current"'; ?>>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                </li>  
    <?php endforeach; ?>
</ul>
