The stats on Ledson there are pretty damning, but as others have pointed out it's how he's being coached to play.
Of course, any manager worth their salt would see that conversion rate in the data and immediately stop trying it. In fact, they'd have probably had their analysts keep tabs on execution success in training matches way before actually trying to use it as a tactic in a live championship match, let alone a season's worth of them.
What do I know though.
Like most things at the club, it's just not a well thought through approach.
