I believe that we created an atmosphere where young players cant step up. Vidal, Rakitic and to a lesser degree Busquets make that impossible. Its far too easy for a manager to go the easy route, there cant be growth without taking risks.
As I said, we need to get rid of Vidal and Rakitic first (and get one decent replacement at the very least). It makes no sense selling Arthur right now - not when hes already a good squad player (which is not nothing). Just imagine Busquets, Pjanic, Vidal and Rakitic next season. Thats uninspired.
