The manager feels teams returning from midweek European matches should be given more time to recuperate.
The Blues are currently preparing to play their third game in eight days, after returning from their midweek Champions League match in Turkey to face Fulham in the Premier League on Saturday.
"We all prefer to play game after game after game — but we all want to play game after game after game with equal conditions for every team,” Mourinho said. "Every team in the same country has the same privilege to be a little bit protected in relation to European matches. It makes the players' job difficult — not my job. I don't play. I could play a match every day and it's not problem for me or the people who make the fixtures."
After Chelsea’s 1-1 draw against Galatasaray in the Champions League, Frank Lampard called on the Premier League to address the schedule when teams are returning from midweek fixtures in Europe.
"Frank Lampard has a right to speak. He's played an unbelievable number of seasons with this club,” Mourinho added. "He's played more than 100 matches with the England side. He's not a man that normally speaks a lot. He's not the kind of player who is trying to show an opinion.
"When a player like him, and a man like him, express his feelings like that I think this country should listen. It's not a problem for my legs, it's not a problem for legs of people who make this decision, it's the players' legs. I am nobody and my legs are fresh after the last match. I didn't sleep a lot but my legs are fresh. For players, it's different."
