I’d advocate zero heading in training and make it exclusive only to match days. It’s needless damage and clearly very detrimental to long term health. Too far gone to remove it from the game though.
Then we’ll have VAR involved when it’s questionable if a headed goal was intentional or if it just went in off someone’s noggin or neck, as in where does the head end and the neck start. Fucking hell.
But, as I said, where, for delineation purposes, does the neck end and the head begin? No worries, VAR will have all the lines all over it. Fuck, this isn’t an item yet, so, yeah, just hypothesising. Oh well, it’s what makes OA go round.
