Reviving this older post. My striker from first season who missed an enormous amount of chances is right now the star in the second season. He is the topscorer in the league and is third on the ratings with a solid 8. In the first season he only scored 6-7's mostly. Right now his numbers are:

League: 9 games, 8 goals, 1 assist, 1MoM
Champions league: 5 games, 9 goals, 5 assists, 2 MoM
Cup: 2 games, 1 assist (of course against a higher level player with some very unfortunate results)

Overall this striker has 1 goal and 0,5 assist per match which makes him a very good striker. At the end of the first season I was so prepared to sell him
