The Blues boss, speaking to the media at Chelsea’s Cobham training ground on Friday afternoon, said that defender Nathan Ake was the only absentee.
“It’s difficult to say why we have few injuries,” said Mourinho.
“We struggle to keep them fit. We try our best. I think it’s a bit of everything.”
He continued: “For us every competition is important, so we don’t rest players and we try to play with our best team.
“Every player in my squad is fantastic and I’m so happy with all of them. The only risk we don’t have is complacency.
“My untouchables are the ones who aren’t playing, they are responsible for what we are doing. They are all ready to help.”
