Custom posts type loop linking to standard post title

Hi,
I have a little problem with custom posts type loop.

I would like to display my custom posts type after standard post article. I would like list of custom posts to be genereted by tags – only custom posts with tags same as standard post title.

E.g. standard post title: Cristóbal Coló
After this post I want to display custom posts with “Cristóbal Coló” tag.

I should, I guess, put some linking code to standard post type to my custom posts type loop. And I dont now what this code should be.

My custom post loop:

<?php
	$args = array( 'post_type' => 'product', 'posts_per_page' => 10, 'product_tags' => 'krzysztof-kolumb', 'order'=> 'ASC', 'orderby' => 'title');
	$loop = new WP_Query( $args );
	while ( $loop->have_posts() ) : $loop->the_post();
	the_title();
	echo '<div class="entry-content">';
	the_content();
	echo '</div>';
	endwhile;
?>
