If you over trained your players yesterday I am pretty sure you was aware that wasn't something usually and that was a glitch/exploit. Do not expect to cheat and win. Also you have to understand that one over trained team can affect up to more than 100 other teams in 1 single season so do the math and decide if it was a good decision or not.
As for rewards to stay on Topic the reward for yesterday was 5 green, red, blue boosters + 5 tokens.
