Wenger acknowledges that Sunday’s opponents have reined themselves in.
“They have become more sensible with time because they realise it's only a short-term situation,” he told arsenal.com.
“You only have to look at what happened to Portsmouth and Leeds. You only look at clubs who have unlimited resources but all the mismanaged clubs died before. Nobody survived.
“What’s surprising is that what looks sensible looks crazy,” he went on.
“I'm not the only sensible person but the fact that I manage a club in a sensible way looks crazy. The biggest reproach I get is ‘why do you manage the Club in the right way?’
“The fans want big players on the pitch and they want to win football games - I can understand that. But I'm responsible for the future of the Club.
“I can understand why Chelsea manage in their own way because they can support the deficit. But we can't.”
