Alfredo Morelos is the man with the shortest fuse in football and was sent off yet again for Rangers in their Old Firm defeat by Celtic on Sunday.
The irate Colombian can be depended on to explode at the merest hint of provocation and reacted to a slight bump by Scott Brown by elbowing him straight in the face.
Steven Gerrard was left shaking his head in dismay and after seeing the striker walk prematurely down the tunnel for the fifth time this season, said he couldn't defend him anymore.
There are a number of statistics that shame Morelos and put his ludicrous diciplinary record under the spotlight.
He currently has more red cards than any other team in the Scottish Premiership this season.
In fact, the combustable 22-year-old's five dismissals is more than there were in the entire World Cup in Russia last year (4).
When you consider that 736 players were in action at the tournament, his indiscipline is even more staggering.
He also now has the dubious honour of breaking the European record for the most red cards in one campaign.
The fifth meant he overtook team-mate Ryan Jack, though two of his four were recinded, and notoriously fiery Real Madrid defender Sergio Ramos.
In 27 matches this season, Morelos has 17 goals, four assists nine yellow cards and five reds.
Having left his side battling with ten men against Celtic on Sunday, in a game they eventually lost 2-1, Morelos is now facing a four game suspension.
By the time he has served the ban, he will have missed a grand total of ten matches including 4 hours 13 minutes of game time in the matches he's been sent off in.
Given his undeniable ability as Rangers' main goal threat, their season could have gone entirely differently if he'd managed to temper his aggression.
