following on from the Mane red card discussion here is my rant on a similar problem which nearly always goes unpunished.
When will the football authorities start taking seriously the dangers of the deliberate "tipping" of players when they are airborne. It seems an accepted practice when the ball is in the air ,particularly from long balls from defence, for attacking players to look at the approaching defender ,and the once he jumps, then back into him whilst bending over therefore tipping them forwards so they drop to the ground.
Sooner or later a player is going to land on their head or neck with catastrophic consequences * and yet football ,unlike Rugby, seems unconcerned since the normal "punishment" is a free kick if you're lucky.
* spinal cord injuries are very unpredictable and are often a matter of "luck" regarding how much damage is done by the what appear to be identical incidents.
