Exactly while the philosofy of the manager is also very important, something many here for some reason overlook. When Louis van Gaal became Bayern's manager, where there's always immense pressure to win throphies, he made the likes of Muller and Badstuber starters, who were unknown at the time but that doesn't matter to him. Frank de Boer did the same at Ajax and made the likes of Eriksen, Boilesen and Alderweireld, who lost his starter place under the previous manager, starters. Some people say they are confident AVB will intergrate youth (if he gets the time). What this belief is based on I don't get as he's only been a club manager for two years and he hasn't made any promises regarding intergrating youth. There was a similar belief by some in Ancelotti while his eight years at Milan didn't suggest he finds intergrating youth important. So the manager's philosofy plays a key role as well.
