Look at these two games,played in the same week(same game shape)
but still quite different playing styles, some teams fit better to a tactic and some opponents also ;)
And then random plays a role in two games evaluation, at least for my team i could say that there a fewer assist but not so much and i go through a lot of games today for moutlinho. And fewer assist, don't mean weaker impact in the offense maybe it is just not so easy to spot.
