The two teams will face off over a two legged quarter final after the international break.
And club legend Futre believes the team deserves more respect and hopes the Porto players will use these reports as inspiration for the two games.
"How did I know? It's in the English press and I called later to confirm.
"Porto players have to run like never before in these two games. Do you know why? They think they have already won the tie. They celebrated.
"When I spoke to the person I was disgusted and I would give anything to play against Chelsea.
"FC Porto players have to die on the pitch, they think they are already in the semi-finals. They celebrated in the morning when they saw they got FC Porto. They can get through, but they have to sweat blood."
