Arsenal boss Arsene Wenger says Claudio Ranieri deserves greater credit for Chelsea's success in recent times.
"Other countries are trying to analyse why the English Premier League clubs are so successful," said Wenger.
"They came to the conclusion it is not only the money. As well it is the face they have of the manager.
"Chelsea is a little bit of an exception, but only recently. Mourinho stayed two or three years and Ranieri stayed five years. And Ranieri has been the foundation of today's team. It is Ranieri who built this team, not anybody else.
"It is not down to me to say that [Mourinho has received too much credit]. I just say tomorrow you never get too much credit because Mourinho certainly deserves credit but maybe Ranieri didn't get enough."
