Hi there,
if you run a Pagespeed test on your site like this:
https://pagespeed.web.dev/report?url=https%3A%2F%2Ffifafootballworldcup.live%2F
It will provide you with Opportunities and the supporting diagnostics for improving site speed.
This is how i read your report:
You have a high Total Blocking Time of 400 ms
which is primarily caused by the render blocking resources listed under: Eliminate render-blocking resources
and impacted further by the: Avoid an excessive DOM size that needs you to Reduce JavaScript execution time
You can see more detail on this by running a WebPageTest:

Actions:
As you’re using Litespeed for your optimization you should check with their support on how to:
Eliminate Render Blocking resources. Not just compress and cache them but look to defer the loading of unncecessary CSS.
And secondly how to defer the loading of Javascripts so they do not load before the page is displayed.
