There has long been a suspicion amongst football folk that goalkeepers have to be a little crazy to spend their career between the sticks.
And one shot-stopper in the United Arab Emirates (UAE) Arabian Gulf League has just provided yet another piece of evidence to support that theory.
That's after Ali Saeed Saqr saw red mist, and was red carded, after punching Al Ain’s Colombian forward Danilo Moreno in the stomach after blocking a shot at goal on Thursday night. However, that wasn't the worst of it, as the Emirates goalkeeper proceeded to stamp on Moreno as he lay prone on the pitch.
Check out Saeed Saqr's moment of madness below - we're pretty certain he is heading for a lengthy ban because of it...
It is disgraceful behaviour from the 27-year-old 'keeper and, considering he didn't attempt to disguise either the punch or violent stamp, it is safe to say he had lost the plot by the time teammates managed to drag him away from the scene of the crime.
Whether it was the striker's show-boating as he tried to fool Saeed Saqr, or the fact that he had already conceded five goals by that stage of the game, the switch clearly flipped in the 'keeper's mind as the red mist descended.
We're not quite sure what sort of punishment is heading his way, but he looks certain to be handed a pretty severe ban after what occurred last night.
With the likes of Eric Cantona (kung-fu kicking a fan) and Luis Suarez (biting) banned for nine and four months respectively down the years, you have to think the UAE league shot-stopper is heading for a similar punishment in the days to come.
