Laurent Koscielny says Arsenal need to play without fear on Wednesday if they are going to overhaul Barcelona.
The Gunners travel to the Nou Camp for the second-leg of the last-16 Champions League clash needing to overturn a two-goal deficit to book their place in the quarter-finals.
Barcelona, who won the tournament last season, were not at their best at the Emirates but still had that aura of invincibility about them.
Ballon d’Or winner Lionel Messi bagged both goals in the first leg and he must be stopped if Arsenal are going to pull off what would be one of the shocks of the competition.
Arsene Wenger has come under huge scrutiny over the past month after a string of poor results and an exit from Europe could spell the end of his 20-year reign at the club this summer.
Arsenal were knocked out of the FA Cup by Watford on Sunday and three games without a win in the league has also left them 11 points behind leaders Leicester City.
However, victory in Spain could prove to be the momentum boost needed for the remainder of the campaign and Koscielny says his side need to keep the faith.
“We need to play with freedom and believe in our quality because we did well during the first six months of this season,” he told Arsenal Player. “I don’t see why we can’t [play like that] against Barcelona and for the rest of the season.”
Barcelona, who are eight points clear of Atletico Madrid at the top of La Liga, have never lost to Arsenal on home soil and punters may decide to use their free bet on the Catalans extending that record to book their place in the last-eight.
