How to retrieve custom post type permalink in another cpt?

I have solved it by myself:
I used following codes instead of

<a href="https://wordpress.stackexchange.com/questions/244525/<?php echo get_permalink("football_player' ); ?>"><i class="fa fa-arrow-right" aria-hidden="true"></i></a>

I used this code:

<a href="https://wordpress.stackexchange.com/questions/244525/<?php echo get_permalink( $home_starting_player ); ?>"><i class="fa fa-arrow-right" aria-hidden="true"></i></a>
