We clearly are on the same page about young players. As for Cole, I think there is a feeling that he could be a great player and, naturally, people are enthusiastic about him; I don't think anyone expects him to play anywhere other than on the right side though.
I was really thinking about players like Oscar Bobb, Carlos Borges and Sam Edozie (whose loan/sale appears to have passed). I think Bobb has more to his game than Kayky, but it always remains to be seen when the step up is made. As for Borges, he is dynamite at academy level, as is Mbude.
I hope they get opportunities but I am realistic enough to note that we compete on all fronts. I hope that this is the year that we blood a few more in cup competitions (Delap, Mbete, Wilson-Esbrand, Lewis) and also give them minutes in the PL (in games where we are comfortably winning) so that they are ready when called upon. This could be the year, for two reasons: their talent, and our squad size.
We agree in general. Although admittedly, some of those players you mention are just names to me, take your word for it.
Youth players don't just get thrown into a season like that, they gradually build up minutes, in a full team. So I don't expect names that haven't yet featured for us to just come into the team. Kayky had 2 appearances that I remember. Palmer had a few too, 4 in the league. Both of them you can expect to have a few more. Others, need to have those 2 or 4 first.
I've seen quite a few people claim we will use kids when league games are won in 60 minutes. I find that a bit presumptuous myself. Both that many games will be won like that, and that Pep would then use kids there.
