Fantasy Premier League 2019 -20

Context

Hi,

This is my first year at Fantasy Premier League. I have created this database till the GW21 of EPL 2019-20. I was intrigued by the data intensive nature of this game and decided to jump into this.

Content

The database includes the player names, team names and all the FPL related stats for each player in every gameweek.

Acknowledgements

All the data has been extracted through the FPL API.

Inspiration

I want to predict the potential points of a player using this data. Using this I can calculate the opportunity cost I would be incurring if I select a player A over player B.
For instance,
This season, the top 6 GKs are seperated by just 5 points till GW21. So, is it worth spending the extra bucks on a different GK among this top 6?
