Hello MATUTOicek ,
As I know you cant' do it in a single SQL query because the calculation of total point number is dynamically done for each season. This total points number is not saved in a SQL table.
If you want to do it, I think that you'll have to create PHP code in order to calculate the total number of point of each team. After that, you'll be able to select only the 1rst one. You can have a look on the 'table' PHP code where this treatment is already done (but in several PHP lines).
