Coding for a FIFA Pro Clubs football ESports League

We have an ESports FIFA Pro Clubs league for PC created on our website but we required 2 or 3 unique functions added to our website to allow to maximise our websites potential.

We are using Wordpress with the Arcane theme (There is 2 Arcane Themes, it's the esports one by skywarrior) .

What do we require?

The theme supports user account creation which is fine for us but we need a stats part attached as a sub heading from this section which is linked to the match reports we submit once a game has been placed.

We also require an area for the managers of that fixture to submit screenshots of the stats.

Finally we would like an area to compile stats, this is to show top goalscorers, top assists, clean sheets and alongside yellow and red cards.

This theme supports coding. You can find it here:
