It depends on what you count as success. If it means trophies... Right now, there are basically 10 teams with money to build a strong team (RM, Barcelona, Bayern, BVB, ManUtd, ManCity, Chelsea, Juve, PSG and Shakthar), of those, 7 proves stability and long term thinking means trophies (RM, Barcelona, Bayern, BVB, ManUtd, Juve and Shakthar). If success is a better position then they would have been... Arsenal, Brasil, Corinthians, Udinese, Porto, etc.
