The Blues crashed out of the Champions League at the last-16 stage on Wednesday night after Paris Saint-Germain edged into the quarter-finals thanks to a 2-2 draw in west London.
Chelsea midfielder John Obi Mikel missed the European clash due to a knee problem, but Blues boss Mourinho added there were no further fitness problems following the PSG game.
Asked if he had any fresh injury concerns at his pre-match media conference at Cobham training ground on Friday afternoon, Mourinho replied: “No.”
The 51-year-old Chelsea boss divulged a conversation that he had with one of his medical staff following their exit at the hands of Laurent Blanc’s side.
The doctor in question suggested that Chelsea could suffer from some mental and physical fatigue because of their Champions League disappointment.
However, Mourinho was never concerned that any of his Blue squad would go missing following the 2-2 draw.
“My doctor told me after the game, maybe tomorrow we have a few injuries. Why? Because we lost and people are sad.
“Maybe tomorrow we have a couple of injuries. I told the doctor that I don’t believe. Zero injuries. Everybody wants to play.”
Mourinho added: “My players are not like journalists. Some write bullshit and then don’t come to the next press conference.”
