The passes or game situations aren't the issue. These sort of passes have to be in the face of the defenders as the attacker is normally right on the line and just needs to slightly poke through to score.
The issue is with the players in question, but the obvious one here is Riki. I would be surprised if he's caught anything more than 20% of those passes, it's almost certain he'll drop it. If he catches them, he normally scores. But it's another one of those situations where you wonder if they genuinely practice it at training and, if they do, how does he seem to so consistently drop them during games?
