Porto won the first leg 2-1 in Portugal and Falcao scored once in that game.
“I had the happiness of scoring the goal that gave Porto victory in the first leg, so that was a beautiful experience in my sporting career,” Falcao was quoted as saying by UEFA.com.
“Arsenal are always going to be the favourites, I think, but at this stage of the Champions League the matches are really closely contested.
“We are conscious of the team we have and of the capabilities of our squad and we have a strong desire and conviction that we can go through to the next round.
“I always followed the Champions League and I think it’s the most watched tournament in the world. I was dreaming of it as recently as 10 months ago, before I came to Porto. I was watching it last season, so yes, I dreamt of playing in it.”
