Chelsea boss Jose Mourinho fears their Champions League push will hurt their Premier League chances.
Chelsea face PSG in the quarterfinals.
Mourinho said: "Paris is a team with very good players. Paris is already a champion and this is an important advantage. They already think about Chelsea and not Nice.
"For us, it is different in the Premier League. All matches are a final for us. Against Crystal Palace it will be a final.
"Paris is the favorite thanks to this small advantage. They have no experience in the Champions League but have quality players. They have an outstanding attack and this is very important."
