Its a 50- 50 this one for sure. He will probably have a few clubs interested that will be a step upwards.
Something is not right about it, this craving for instant success,wealth & glory is a rare thing .
I reckon he would risk stalling his career with a move away now.
Another year with us to make him even better seems the more sensible footballing career decision.
Hopefully he is also thinking like this - there are plenty of examples of careers gone down the tube - Wyness to Hearts springs to mind - Lee Miller to Middlesboro - etc
