Is there an explenation?

I just had two consecutive matches in which the opponent's goalkeeper is a monster and has a score of 8.5. The first one I won 2-0 versus a tream 60% less than me, so I had 20 chances to score but only converted 2. The other one I lost vs an equal team in value. I'm just curious because I have a on-fire goal keeper which has the play style maxed, but he never is a monster in my matches. Maybe there is some special food that those GK eat .
