It doesn't seem to be his natural demeanour to be that voice though .
At age 25 if he was that type of personality, I would have expected to have seen signs of it by now, and he hasn't shown it. Whether it is a confidence issue or self-belief issue I am not sure, but he doesn't appear as though he is prepared to take that leap . I'm pretty sure he will be getting the right encouragement from Pep, but I don't get the impression that John truly believes in himself.
I would love to see him exude confidence to match his ability but I fear it will not happen overnight.
Possibly an extended run in the team will help .
