On Jones, he shouldn't stop believing he's good enough to play (he is) and pushing for it and should continue to be arrogant on the pitch (It's fun to watch and what you get from some of the best)
I don't think anyone would disagree with that Chris. As I said above, Rossi is, for me, overstating the manager's approach with players, but the manager is a master of gently doing exactly what he describes. For the most part the players love him while he's doing it.
We're going off topic here, and in fact it's maybe an interesting discussion in its own right on a separate thread (or the Klopp thread even)... so we can maybe draw a line under it here. But it does bear underlining from a club culture point of view. This is a theme that runs through everything - from the standards they want set from senior players (we saw Lallana lionised for it when he left in recent weeks), to the qualities they won't compromise on in the players they recruit from other clubs, to the coaching staff... the demand on the players is that they stay humble, stay hungry, work hard ('intensity is our identity'), and continuously learn and improve their game.
So from that perspective, the players we've discussed to Tsimikas, Fabinho, Robertson, Shaqiri, Origi, whoever - that's what's expected of them. If they can't hack that then they leave. That might be rationalised as the player seeing their own limitations and moving on, but if the staff are on record as saying they want to leave a senior England international leave while retaining a prospect in the senior match day squad (during a league title push), it's quite a compelling message to the player that he's valued, and if he gets his head down, that he'll have a chance at a career here.
The situation was identical for Jones, Camacho, Williams, Woodburn, Trent - whoever might be on the brink of breaking through. They might get no luck while waiting, but it's a simple fact that they have to wait patiently for their chance. Curtis is cocky, and that's good, but he was on public record saying he wanted to get in the first team side, to the extent Klopp commented on it (repeatedly - two examples are listed above, but there's a reason he says "He has no problems with confidence"). Curtis has since backed up the attitude with performance and professionalism to the extent he now has a squad number. That's a credit to him and to the staff. And from that point the expectations on him will only ramp up. That's no different to the expectations on any other senior player - it's the central tenet of Klopp's Liverpool - that we are 'mentality monsters'. That applies from top to bottom, and it doesn't stop the minute you assert a first team claim. They all enjoy their work, but they're serious and respectful in a way that's become distinct from their competitors in recent years (I think so anyway).
I'm not suggesting Curtis isn't doing those things, and I'm not suggesting those things are mutually exclusive to having self-belief. I'm saying that if he's arrogant, and he channels it the way he's being challenged to by the management and coaching staff, he'll go on to be a serious football player for this club.
