He was probably wanting to show his former fans that he was better than their chants of him, an dbeing substituted in front of their jeering without managing to score a goal was probably humiliating to him.
What he should have been more upset at was letting the club and us down instead of caring about what he looked like to newcastle fans. From the reports of how he returns to Newcastle so regularly etc, I don't think he has actually mentally stopped being a Newcastle player yet.
This is the last straw for me.
In the beginning of the match, I thought he finally showed some passion and started really trying. But it turned out it wasn't passion for the club. His little tantrum at the end just disgusts me. The substitution, rightfully or wrongly, was the manager's decision and he should respect that. I'm not saying he had to look happy, but as a professional player, what he needs to do is go sit on the bench, and support his
team. Instead, he just had to throw a temper tantrum and leave while the match was still going on. He obviously doesn't give a fuck about Liverpool. It's all about him. The Andy Carroll show. Poor little Andy got booed by his beloved Newcastle fans and he just couldn't deal with it.
Some fans don't care and say it shows passion or whatever, but I can't stand that kind of attitude. In the past I used to see players from Chelsea or City behave like that and I always thought 'what a pathetic club to allow its players show such disrespect', and I was glad we are not like that. But maybe I was wrong. And I hated seeing that.
I know he didn't want to leave Newcastle and was homesick and I tried to be more understanding when he just strolled around during matches or walked away from the goal while his teammates worked hard to keep the ball in play. But you know what? I'm done. If he doesn't want to be a Liverpool player then he shouldn't be.
