I think It can go either way , he certainly needs to sort his discipline, he had a reputation as a walking yellow card but instead of improving that this season it seems to have got worse. I think he has enough talent but with him being part-time and his ill-discipline isn't working for him at the moment.
I'm terms of releasing his wages I'm not sure he will be on much now, I doubt he would have been earning much before and I would expect that to have been reduced a fair bit with him going part-time, they should have done anywhere.
I would expect him to be in full-time during his uni holidays which will most likely when the decision will be made, it will be a big period for him. He still needs to pick up his performances in the mean time tho.
