It's not just your character that gets unfairly rated. I was playing for Italy against Germany in the 3rd place playoff of Euro 2016 and Osvaldo scored 4 goals in a 4-0 win. He got 7.5. What more do you want from a striker in a major tournament?
For the record, we were knocked out on pens by Portugal in the semi-final, Spain won the final.
In 3 seasons at Bordeaux I won top goal scorer, assist leader (twice) Ligue 1 player of the year, Cup assist leader, Cup best player, Ballon D'Or winner, League winners once, runners up twice, Cup winners once, Champions League winners once, Man of the Match 25 times in the league plus more in Champs League & Cup... and my overall average rating was 6.8. 6.8?! Do all those honours suggest above average to you?
