He does have humbleness and self discipline I dont doubt that but thats not the part of his attitude that worries me
If you look at two key midfielders from Peps reign in David Silva and Ilky Gundogan they are the epitome of the personalities that Pep wants......humble as you say but also absolute killers on the pitch (Silva even had a little nasty streak in him which went under the radar - for me he eclipses KDB as he was never less than an 8/10 everytime he stepped onto the pitch).....you need that aggression/deisre to win, willingness to run through brick walls for whoever and whatever....at such a young age I wouldnt expect Palmer to have everything BUT look at foden - he was driven from the moment you saw him step onto that pitch - even in the friendlies....something about Palmer is lacking in that sense at present -he is languid as Ive mentioned before.....he doesnt seem to have that killer/drive instinct in him
Im NOT saying he wont get it....Im just saying at present he hasnt got it and needs time to develop it.....a year at a lower league club or even a mid table prem team might help him develop from a kid into a man as he isnt there yet.
Technically he is obviously very good.....but so are many many youth players
