I don't think he lacks the talent, I think he just needs to grow up a bit.
He reminds me of Stones 3 years ago. Still acting like, and making the mistakes of a 20/21 year old without noticing he's 25 now and a seasoned pro. Stones was always playing passively and looking sorry for himself when he made a mistake and so does Jesus whenever he misses a chance you can see him getting angry with himself and carrying it around all game and he too often plays passively, avoiding chances as often as going for them.
I think Stones had a really hard year off the pitch and it toughened him up a lot and maybe made him realise he was stronger than he thought. I don't know what's going to make Jesus go through the same metamorphisis but he needs it ASAP.
