Leaving is one thing. Herbie, flegler and palasia have all done it, but they didnt slag off the coach and club management along the way. After all, some of the peole you just antagonised might be a future coach/football manager or team mates, and he spread his venom pretty wide here.
I also think if he was half as good as he thinks he is, he could have bagged a bench spot at least, and used it to promote his abilities to other clubs, if nothing else. I also think mam was no certainty to become the full time 5/8 when he left.
Hopefully he learns from it, but if nothing else, it serves as a good example to young players of the difference between being a "potential" star and an actual first grader.
For all the promise, it means nothing until youve made onto the field.
