The Londoners have spent huge sums of money on transfer fees and wages to attract some of the top players in the world since Russian billionaire Roman Abramovich bought the club in July 2003, but Mourinho expects Manchester United, Liverpool and Arsenal to all spend more than the Blues in the summer transfer market.
Mourinho told Chelsea magazine: "The spenders will be Liverpool, Manchester United, Tottenham and maybe Arsenal. I don´t know, but it won´t be Chelsea for sure. So maybe at the beginning of next season they will say that Chelsea are not the favourites any more because the club did not spend so much money."
