Difficult one that. I think Pep has looked after Foden a bit more than others. I think that is testament to Fodens ability, attitude but also his links to the club which we all know Pep rates very highly. Everything I have read has told me the club went out of its way to showcase Foden to Pep, so its always been in his mind since he arrived. Foden isn't in the squad just as a token fan though, the lad is one of the best in the world at his age.
I think Pep will show more faith in some youngsters than others, the likes of Doyle for example will have a higher chance of making it here than say Nmecha, thats not to say that Pep is going to just look after someone because he has City royalty in his blood and he runs a lot but those weigh heavily in Doyles favor, he can play as well. I know there are a few on here that believe that Pep has a "spanish agenda" and is pushing Garcia and Bernarbe etc ahead of others but I disagree with that.
In terms of doing a "Sancho", I think we can say that perhaps we have seen that with Matondo leaving and maybe Braaf will do the same, we can argue all day about whether that is the clubs fuck up by not playing them etc but we don't know the full story. Whereas I see the likes of Palmer, Doyle and Delap sticking around and really pushing themselves before just upping and leaving because its a "trendy" thing to do and go play in Germany e.g. Matondo, Sancho, Reiss Nelson and so forth.
