Chelsea manager Jose Mourinho has hit back at Fabio Capello, after the former England manager claimed that he lacks longevity.
Capello hinted earlier this week that players become burnt out under the Portuguese coach after a spell of 18 months to two years working with him.
However, Mourinho has stated that the Italian should respect the work of his fellow managers.
"I read what Capello said. I think a coach with his story had better talk about football without comment on the work of his colleagues," Mourinho told Gazzetta dello Sport.
"I could have commented on his job as coach for England or the Russian one, and I never did. Because I prefer to respect the negative moments of my colleagues.
"I prefer to talk more of Fabio Capello in the many beautiful moments of his career, full of extraordinary success."
Chelsea won the Premier League title last season under Mourinho, but four defeats from their opening eight games of this campaign currently leaves them 16th in the table.
