Can anyone see this realistically happening? They can stop it in training but there is still the risk in games. It would change the game completely if they banned heading, would you want to watch football without heading? It might improve the standard of football but some teams rely on the route one method and they would feel penalised if heading was banned.
There's nothing better for me seeing a great headed goal or clearance but it is a massive risk looking at all the evidence piling up now.
