EDIT: explain schema.


First is necessary separate all stats for team in a interval time,
because changes in time for season, years, stats, etc...
Add the match documents, for each match a document. Separate all
for    documents, League, Teams, Ranks, is better for search and
relation    with others team in match, rank...
And the solution is MySQL I'm not so sure about that, because if you 
have a lots data in match, league, teams, ranks... Is Better documents with all stats of any team, or all rank in any interval time
because in MySQL you need JOINS for that.
