Disagree. If anything it's Isak who should know not to leave his leg in there. I'm not speaking about the proper penalty for that tackle in match either, but about Slot's attempt to damage Van den Ven's reputation.
Now if intent doesn't matter then there's double the reason not to call the tackle reckless, because whether it was reckless or not doesn't matter.
But intent doesn't matter is nonsense. What would the word "control" mean if control wasn't associated to a presumption of good intent? This is an unfortunate incident that for malice doesn't come anywhere near the bad old days of the league. It just happens to affect Slot's misfit star signing.
