Mourinho isn't preparing for matches very well, according to Capello.
Former Roma, Juventus, Real Madrid and AC Milan coach Fabio Capello says Jose Mourinho's system doesn't last long and only works short-term.
"Mourinho burns out his players after a year and a half, at most two years," Capello said on Fox Sports.
"I had already heard it when he was in Madrid and now we have confirmation in London.
"It is true that Chelsea are paying for some of their absences - like [Thibaut] Courtois - but there have also been tactical errors from the coach, who this year is not preparing for matches very well."
