He just doesn't seem to have the ability to get it out of the keepers reach right now. You see the training drills they post where he bags but it's never the situations he misses that they're working on. You'd hope they're working on the weaknesses too and imagine they are but it's still a weakness.
If we had the choice of any of them, one on one with the keeper, I can guarantee no one would choose DCL in recent years. Just lost that clinical touch.
