I have forked the repository and fixed a few bugs as I noticed it is not maintained for 4 years. I have now reduced the numbers of API calls needed to fetch the team logos (that are now directly obtained by the HTML code) and reduced the number of API calls to fetch the table and the scores.
The table APIs does not include a “refresh” time (as they maybe did return times ago) and this causes an infinite number of call to it.
The forked repo is here: https://github.com/0m4r/MMM-SoccerLiveScore
I have not made a PR as I d believe the original one is abandoned.
