Such a decision would open the door for Hilario to make his first Chelsea appearance since August 2011 - when he kept goal in a 3-1 win over Norwich City at Stamford Bridge - and Mourinho has full faith in the 38-year-old's ability to step up.
"It's a big dilemma," he told the club's official website, "especially with players who are always looking for penalties and go for contact with the goalkeeper, it's even more dangerous.
"I remember when Hilario played against Barcelona in the Champions League [in October 2006], he went in goal and he had to answer so it's a good thing to have a second or third keeper with experience, who goes into the game ready."
