posts-teaser-loop with post meta

Hello I need help white the template code. I will show the own post_meta “_total_shares” with the Shares inside the meta_value_num. So whats wrong???

<div class="su-posts su-posts-teaser-loop">
	<?php
		// Posts are found
		if ( $posts->have_posts() ) {
			while ( $posts->have_posts() ) :
				$posts->the_post();
				global $post;
				?>
				<div id="su-post-<?php the_ID(); ?>" class="su-post">
					<?php if ( has_post_thumbnail() ) : ?>
						<a class="su-post-thumbnail" href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
					<?php endif; ?>
					<h2 class="su-post-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
                    <div class="su-post-meta">Christian <?php _e( 'Posted', 'su' ); ?>: <?php the_time( get_option( 'date_format' ) ); ?></div>
                    Likes <?php get_post_meta('_total_shares'); ?>

				</div>
				<?php
			endwhile;
		}
		// Posts not found
		else {
			echo '<h4>' . __( 'Posts not found', 'su' ) . '</h4>';
		}
	?>
</div>
