Money has been a factor. Look at where the titles have ended up. And don't pull Leicester out of your arse, what they did was remarkable but they didn't repeat it. In general the biggest prizes end up at the clubs with the biggest resources. Chelsea and City were nowhere before the billionaires took over. But that doesn't mitigate all the failures over the last 10 years and the main issue is right now we do have the resources to compete and we are still failing to.
