Porto defender Pepe says they deserved their Champions League win against Arsenal.
Porto win the first-leg of their Champions League round 16 tie 1-0.
Pepe said, "We knew it was going to be very difficult, they run a lot and have quality, we knew that to beat them we had to run twice as hard. We played a great game and won with Galeno's goal.
"They were looking for the ball, we had to take advantage of the moment and wait for opportunities.
"It's going to be even more difficult away from home. They try to attack all the time. We have to be focused, even more than here, to seek qualification."
