Reports have suggested the French giants are looking to sign the duo in the summer, after watching them fire 22 goals between them to carry Chelsea into contention for the Premier League title.
But ahead of the two sides meeting in the first leg of the Champions League quarter finals on Wednesday, Mourinho has demanded £300million before he will consider doing business.
“No. It’s not irritating. No problem,” Mourinho said.
“If there is Financial Fair Play, they don’t have money to buy them.
“If there is no Financial Fair Play and they threw something crazy, £300million for both, I think Chelsea has to think about it.”
Chelsea are set to take on the French champions on Wednesday, looking to bounce back from a shock Premier League defeat to Crystal Palace on Saturday.
After the game Mourinho wrote off Chelsea’s title chances for the season, saying: “I think now we have lost any chance of finishing first.
“Now we depend too much on other results. Too much. When you depend a little it’s possible, but when you depend a lot, I don’t think it is.
“Six matches for us, and others with matches in hand … I know mathematically it’s possible, but one thing is mathematics and another is reality. We are not [contenders]. I don’t think it will happen: we depend too much on other results, and the other teams control what they need. I don’t think we can win the league now.”
