Ratings is the mark out of ten each player gets, highest average ratings are recorded, just screen shot them. And if there is a draw in the ratings then the player with the most MotM wins
And to manipulate the motm, say my best player is on 7.8 after 50 mins but two players are ahead of him on 8.2 and 8.4, then I'd sub the two players in the hope my 7.8 guy would start scoring and win the MotM
