Most teams who have been successful over the years have also had a decent policy of bringing through young players, including Pep's Barca. And us, in all of our periods of relative success, in all our history, prior to the takeover. We were known for it.
We allowed Pellegrini to completely disrespect that tradition & it has most likely cost us several young players we wanted to keep.
Pep's recent actions with Foden etc, plus kids playing some high profile games last season, is close to being a decent balance. Unfortunately, Pellegrini had already ruined our best crop of youngsters for decades, prior to Pep arriving & rather than handing over a collection of possible squad players for his first season, handed him a bunch of mostly aimless drifters with no confidence.
