Liverpool and Manchester United have reportedly held discussions about a plot involving Europe's biggest football clubs to join a new FIFA-backed tournament that would reshape the sport's global landscape.
Spurs are included as one of those clubs, but Mourinho was coy when asked about the proposal ahead of Thursday's clash with LASK.
"I leave it for Mr Levy," Mourinho said when asked for his thoughts on the European Premier League and instead turned his attentions to the Europa League - which he has won twice as a manager with Porto and Manchester United.
"In this moment, we are playing Europa League. We are going to try [to win it]. It is the third time I have played this competition and the other two times I won it. So the record is great, I have never been knocked out.
"Of course, I lost a few matches and we know it is difficult. The group stage is tricky, then you go to the knockouts, then teams coming from the Champions League - which in my opinion is very unfair.
"It's a long competition, for now we will focus on the points we need to qualify from the group stage."
