The Italian manager thought that Mourinho had would burn out his players in two years, and the poor run of performances that is happening a the club could confirm his theory.
"Mourinho burns out his players after a year and a half, at most two. I had already heard him when he was at Madrid and now we have confirmation of this in London," he said.
Capello claims that the Portugese manager isn't going the right way about preparing for matches this year, even though injuries aren't helping the club leave the crisis.
"It's clear that Chelsea are paying for a few absences like Courtois, but you can also see many tactical errors being made by the manager, which he isn't preparing very well for matches," the Italian manager said.
