"We played very well but when you have six or seven chances to score and you don't take them it's difficult to take. But that's football, and we have to look forward now," Mascherano was quoted as saying on the official Uefa website.
"We know how experienced they are. They have a lot of clever players so I think the next game will be the same because they defend so well.
"But we have a lot of players in attack that can put on a good show, score goals and win us the match. Obviously with all the Barcelona supporters behind us we will try everything to get through to the next round."
"I have both Messi and Cristiano Ronaldo as my idols. If I can take a little of each player's game and make it my own, I would be very happy," the young star laughed, in Thursday's interview with Globoesporte.
One particular aspect of the Brazil international's game which has invited comparisons with Ronaldo is his style of taking free kicks, but Neymar insisted that it was merely coincidence.
"There are players that try to imitate others, but at free-kick time it is a personal thing. Every person has their own technique and routine when they stand over the ball and I have mine, I am not trying to copy anyone."
