Watch AS Roma Vs FC Porto UEFA Champions League Live Stream: Start Time, Preview, Round Of 16 1st Leg Online

The struggles for Italian side AS Roma have continued in the 2018/2019 domestic season, with only two wins in their last five matches, per Soccerway -- including a 7-1 drubbing at the hands of Fiorentina in an Italian Cup match just two weeks ago. But they squeaked through the UEFA Champions League group stage with a 3-3 record, entitling them to open the knockout round against an often overlooked but extremely dangerous opponent in the Portuguese leaders and defending champions, FC Porto. They will engage in a Round of 16 first-leg showdown that will stream live from the Italian capital city.

Kickoff is scheduled for 9 p.m. Central European Time at the 71,000-seat Stadio Olimpico in Rome, Italy. The match takes place on Tuesday, February 12.

With former Real Madrid great Iker Casillas minding the net, Porto have maintained a solid defensive bulwark all season in their domestic league, allowing just 12 goals in 21 league games, per the BBC. They have, however, allowed six goals through their six Champions League games — but also lead their league with an average of 15 interceptions per match.

Roma, on the other hand, has been prolific with the ball, scoring 44 times in Serie A, per ESPN, which places them third in the Italian league. Their 11 goals in the Champions League group stage was fifth best among all teams in the competition.

History is not on Roma's side, either. In four European matches — most recently the 2016/2017 Champions League qualifying playoff — the Italian team has never defeated the 28-time Primeira Liga champions, boasting two losses and a pair of draws, per Sky Sports.
