He's not exactly become an automatic starter at Dortmund yet either. Maybe he wouldn't have got the 6 starts for us this season but he would undoubtedly have been involved enough, cup games he would have started plus the odd champs league appearance and theres been plenty of times Sane and/or Sterling have looked knackered but weve had to keep them on due to a lack of alternatives. He could easily have racked up at least half a dozen league appearances on top of the cup games, might only have been 10/15 minutes but it would have been comparable to what hes seen at Dortmund. Foden and diaz play in a position we are fully stocked in, making it harder for them, there would have been less in front of Sancho as a more natural winger.
Pointless going on about it anyway, if our academy is to be even more successful and remain that way, they'll be numerous Sancho's that come and go in the future, it's part and parcel of it. The key is leaving them hungry to return in the future. Look how many Barca lose or let go every year and the majority of them are dying to prove themselves elsewhere before going back there if they end up good enough for their first team. Our academy is doing fine, it's becomingif it already isnt self sustaining whilst we hunt for that elusive gem that makes it into our side. Were one of the best sides ever right now, the chances of finding somebody capable of fitting into our side on merit so young is monumentally slim and some fans have to recognise that. If we bring just one or two through per generation along with bringing one or two back after them initially leaving whilst also regretfully losing a couple in the process too, then the academy will be arguably the best around.
