Arsenal will have a massive test as they fly out to face FC Porto in the first leg of the UEFA Champions League Round of 16 on Wednesday (February 21).
The Gunners made a return to the biggest continental competition after seven years, and reached the knockout stages after topping their respective group. FC Porto, on the other hand, finished 2nd in their group after Barcelona.

Arsenal are currently flying in the Premier League. Mikel Arteta's boys are just two points off the top spot and are in excellent form. They have won their last five matches in the league and will be hoping to continue that in the Champions League.
Porto find themselves seven points off the pace in Liga Portugal and have had their share of stutters this season. Sergio Conceicao's boys have won seven of their last ten matches, but have failed to win against the likes of Sporting CP and Benfica this season. Arsenal will definitely be a massive test for the home team, who need to be at their best to get a positive outcome in the match.
