Higuain was on the scoresheet in their 3-0 Champions League win.
"We are relaxed. The coach has already said that he has never pressured us to score goals. Today we scored and the important thing is that the team won. I got to come on for 20 minutes to help the team and I was lucky enough to get that goal. It's great to score and have everyone celebrate it," said Higuain.
On his celebration, the striker added: "When I went out to warm up he said that I would score and so I went to celebrate with him. Pepe has been a great friend of mine for many years and has always helped me. I dedicated it to him because I told him that if I scored it would be for him.'
