# Disclaimers
* Based on the previous seasons' statistics.
+ Re-run the codes after several matches in the next season.
+ The data set needs to be updated frequently (i.e., every two Gameweeks).
* The Summer 2022 Transfer Window for Premier League clubs will close at 23:00 BST on 1 September 2022.
+ A possible move of Mark Cucurella (BHA, £5.0) to Chelsea.
* Limitations in the computer memory make the analysis could not cover all possible choices: Use a higher specifications (memory >60 GB).
* World Cup 2022: Including players involved in the competition or not?
* Belut Listrik's statistics in the last season:
+ Overall points: 2,414
+ Overall rank: 272,435 of 9,167,407 teams
