Very heavy wordpress plugin and customization - php

Question

i have a wordpress website and with customization (cache/minify/database), is really quick in frontend, and in backend, with one exception. I use a plugin where it stores and retrieves players stats, carreers, teams etc.
When saving the team's match player's statistics, it needs 5 minutes to show the page reloaded with the data.
Also when retrieving for example team's season data, it also needs a lot of time to show them.
From what i ve seen, it is related with two of my files that do all the work. tournament_match.php, and functions.php. From hosting they said that it gets all tha database and thats why it is so slow
Here is the tournament_match file
<?php
