Firstly, love the game. Thinks its designed fantastically!
The few little issue I have that I think would make a big difference is :
1/ Make the "Top rated" section of the league stats a cumulative score, rather than an average. This would stop players playing 1 game and winning the MVP. Or at least make it only valid to players who have played 50% of the games.
2/ If a player wins the MVP, golden boot or top assists you should get a prize at the end of the season like a bonus 5 skill points.
3/ Should have these stats for cup and champions leagues aswell (not just league)
4/ would be cool to see images for each players, even just a head shot. you could even charge tokens for people to amend the look of their player
5/ would be good to see some variety in the scout list rather than all just the same level across attack/defense and physical skill points.

thanks for listening! (reading!)
