I believe the lad has no intention of injuring the player. He isn't a Ben Thatcher. However, Uefa has got to set a precedent on dangerous reckless tackles. Educate the footballers, tell them that if u go in studs showing, like Witsel did, u risk not only immediate punishment, ie a red card, but also facing a hearing after the game, which may result in a long ban, depending on the severity of the injury. Also, let the players know that should it result in a long term injury or career ending, he will be liable to be sued for damages. It's as simple as that. It's just isn't fair for a professional to have his career ended by some reckless challenge, while the culprit goes on to enjoy full earnings of his career after a 5 months ban. The punishment is just not justifiable.
