The position of the players on the grid is now available in the API.
How it works ? X = row and Y = column (X:Y) Line 1 X being the one of the goal and then for each line this number is incremented. The column Y will go from left to right, and incremented for each player of the line.
Also the colors of the players' jerseys and goals are now available in the endpoint lineups.
You can find all the information about how it works in the documentation.
