The Brazilian has been criticised this week for his showboating at Leganes on Saturday.
But ahead of tonight's clash, Simeone stated: "Neymar is an extraordinary player. He won the Olympic Games after being criticised in Brazil following the first two games. He's found his place in Barcelona to express his talent.
"Neymar has that way of playing. Everyone has their style. I love it. Neymar sings, dances and destroys. He speaks where he has to -- on the pitch."
