Their recent performances have been patchy, however, with three straight draws preceding Saturday's laboured 1-0 win over Valladolid, secured thanks to a Lionel Messi penalty.
Terrier is an unassuming talent, but he delivered the most exciting moment of the first half for the crowd of nearly 58,000 with a thunderous strike from 20 yards out in the ninth minute that was tipped onto the bar by Marc-Andre ter Stegen.
Memphis Depay had been quiet in the first stanza, but he almost broke the deadlock seven minutes into the second half with a snap-shot that sailed inches wide.
24h - As of the 22nd minute of tonight's game against Lyon, Luis Suarez has gone a full day of game time (1440 minutes) without scoring away from home in the Champions League, last netting against Roma in September 2015.
Peace at last between Mourinho and Wenger
Arsenal will be without striker Alexandre Lacazette for the second leg of their Europa League last-32 tie with Bate Borisov. Unai Emery has held heart-to-heart talks with Mesut Ozil in an attempt to finally coax the best of the mercurial German.
"It was also said that we did not score away from home and this year we have done so in big games against Tottenham and Inter".
This match-up also marks the first meeting of undefeated UCL teams in the knockout stage since the 2007-08 semifinal (Barcelona vs. Manchester United).
Of course, Suarez still has his wiles and Leo Dubois discovered that when he was booked for making minor contact with the forward - who got a few rolls in on the turf - to the disdain of Lyon's fans.
Failing to score in Lyon means Barca must win the second leg at the Nou Camp on March 13 and they will be vulnerable should the French side, who like the Spaniards are unbeaten in this seaon's competition, grab an away goal.
Suarez wasn't the only player guilty of erring in front of goal in France. Another nil-nil takes it to extra-time, any other tie and the French side progress.
