Barcelona forward Joao Felix recognises they face the best player in the world on Wednesday night.
Barca are in Paris for the first-leg of the Champions League quarterfinal against PSG, with Kylian Mbappe to lead the Parisians' attack.
Felix said: "He is perhaps the best striker in the world.
"I like the way he plays. Whether one-on-one or going into space, he is very fast and has quality. In other words, he is very decisive and makes the difference in any situation and in any team he plays.
"He and Ousmane Dembl? They are both very good, but football is about duels and not all ten of them win. We have to be good in defence to be able to stop them and the others."
