I agree with the premise, but it's a balancing act when dealing with youngsters at our level, where a couple of losses could be the difference in winning the league (or cup) or not and then you don't want that situation to affect the lads confidence.
Pep knows this and will be careful with him and introduce him slowly.
It's a big leap in terms of standard but, as seen with Oscar, the lad will have to trust the process, be patient and be ready to take his chances when called upon.
The Palmer comparison is a bit different in that he was playing in a team that didn't look like it had any real style of play and seemed to be trying anything to see if it worked.
I like Palmer and think he's a great talent, but there's no way he would've been given the licence to play like that with us, because our style and structure of our play is/was so different.
