Is it pure luck?

[CDL]

4 seasons ago he cost me 2 tokens and he's clearly the best striker I ever had. I won CL and cup last season simply cuz he was unbelievable (he also was #1 in the league in all 3 categories: Top Scorers, Top Rated, Top Assists).. and all that with just 5/6 stars (he always starts season as a 5*, finishing as a scout) ........but really, there is not much strikers like him, you need luck. I tried lots of guys that looked like super snipers on the paper, but I only had 2 real sick scorers in 16 seasons.. he is one of them, the better one from the 2.. I saw that in him since his 1st game, he scored 2 goals, added 2 assists and was rated 10 in his debut.
