“It’s great. We have earned the right to be here. It’s been seven years since we’ve been at the top table for these kind of matches and 14 years since we were able to go to the next stage.
“That’s the challenge. We know what is ahead of us, but we are very excited to face it and to go for it with full belief, that’s for sure.”
After six years out of the Champions League, Arsenal topped Group B, picking up 13 points and finishing four points clear of second place PSV. They are looking to make the quarter-finals for the first since the 2009-10 season.
Porto finished second in Group H, behind Barcelona. They currently sit third in the Primera Liga, seven points off the top. They could be without Iranian striker Mehdi Taremi, who is struggling with a thigh injury.
Arsenal have not won in three trips to Porto in the Champions League, drawing once and losing twice.
