I had that exact problem this weekend...
Attacking player closed down a defender and fouled him just inside his penalty area... It was bordering a cautionable offence but I was lenient; I called him over and stated it was his first and last warning. His manager on the sidelines tells him to calm down, his response was "I couldn't give a s**t". Now, I heard this but decided to ignore it, it was a conversation between him and his manager and one that I could have had a further word with him about, but he seemed a bit annoyed at the fact I'd just penalised him. So, another mental note saved. Game continues.
A few minutes later, same player makes a challenge on the halfway line by jumping in shoulder first. He knocks the player over and player holds his face. I call in the medical staff and straight away I call over the offender. I deem the challenge to be reckless and a worthy of a caution, especially considering I'd only had words a few minutes prior.
I ask the player to come to me... He ignores me. On the fifth attempt, he finally comes over. He's pretty annoyed as you can tell, he just seemed to be that type of character. I point to his first offence, then his second and state that he'd had his final warning and that he was now to be cautioned. I ask for his name... Nothing. I ask again... Nothing. I'm starting to lose patience now I ask him a further three times. He finally gives me his name, albeit reluctantly. As I begin to pull the yellow from my pocket, through a few players he tries to knock the cards out of my hand. The caution was given despite not being able to get the card out. I then decided enough is enough and make him aware that he is now being sent off and he's to leave the field in the direction of the changing rooms... A yellow and then a straight red... Absolutely no need whatsoever for it to get out of hand like that.
The crazy thing was, he then left the field and started pulling posts out the ground and smashing up the changing room, causing damage to the doors. I'm guessing someone didn't get what they wanted off Santa!!
As I sent him off, I then had another player come round from behind me... "You c**t, are you going to send me off now? C***, c**" he kept repeating that word until I asked his name, which he gave me, then he stared again and carried on after I produced the red up until he left the pitch.
I've been playing football for over twelve years, I only referee when I haven't got a game on Saturdays, I also referee on Sunday's. In all those years, I've never seen behaviour like that!!
