They should really have a three strike policy for this kind of thing, next ban should see him banned for a year or more, you cannot keep doing this.
Feel bad for Liverpool honestly, though in fairness they did ok in his absence last year.
Next time and he's out I would think, or the ban would be long enough like two years to be enough to finish him. If he's smart he'll use this time to sort himself out and take responsibility for his actions because if he doesn't the next time he does something like this he's gone. He's had more than enough chances already
