However, the 21-year-old had been a key player in recent months and came off the bench to score Barcelona's final goal in their 5-1 Champions League win over Lyon on Wednesday night.
Lyon's Lopes had to be taken off injured later in the first half, leaving the field in tears after taking a blow to the face, with Mathieu Gorgelin replacing him and making his Champions League debut.
There was a hard spell for Barça at 2-1 in the second half before Lionel Messi - who scored two and made two - wrapped things up for the home side.
Another match for Lionel MESSI and another great showing from the captain.
He combined fluidly with strike partner Luis Suarez and almost put the game to bed at the start of the second half when he beat Lyon substitute keeper Mathieu Gorgelin but saw his shot cleared off the goalline. "I thought Atletico would be a lot stronger, but Juve were all over them and Cristiano had a magical night".
"But every team left is hard, so let's see who we get next".
"Luckily we then got the third goal".
Barca looked unsettled for a brief period after Tousart's goal had put Lyon one goal away from knocking the Catalans out, and the home side defended with an air of panic. The Argentine opened scoring during the 17th minute of the contest, when he fooled Lyon goalkeeper Anthony Lopes with a lovely Panenka penalty kick.
"Barca head coach Valverde was pleased with Coutinho post-match amid his struggles this season".
Lyon coach Bruno Genesio added: "Tonight Messi was in Champions League mode".
"We're relaxed and what we have to prepare for is the toughest test possible, which is what's coming now in the final stage of the season". "Sometimes he is just unstoppable".
