I don't think it's a case that his talent has ever been in question - he's obviously got the talent. It's the other things that separate the best players from those who don't quite make it - decision making, tactical awareness, attitude and all that shit.
It's the sort of stuff that traditionally attacking midfielders tend to struggle with more when they're young and why increasingly we've seen them shunted out onto the wing or even up front - if they make the team at all - in recent times.
The last couple games, however, it's all kinda come together a lot more and then the cute touches, dribbles and willingness to take on shots really come to the fore in a much more positive way.
My favourite moment from the game last night against Porto was just before his assist for Salah's second. He was running into space with Mane completely free to his left. It would've been easy just to hand over responsibility to Mane - who being further wide wasn't in as good a position - but instead he carried on himself and found a killer pass as a result.
Jones biggest plus - particularly for us as a team - is his (seemingly absolute) confidence in himself. Mane free? Meh. Henderson asking for the ball? Meh. Opening for a shot? I'll take it.
We need someone from midfield who will take a few more risks further up the pitch. It's just knowing how to get the balance right and the last couple games it has been.
