The Gunners head into the game on the back of their frustrating goalless draw with Hull City in the fifth round of the FA Cup on Saturday afternoon.
The north London side have not progressed past the last 16 stage of Europe’s elite club competition for the last five years and will have their work cut out against the La Liga champions in north London next week.
Former Arsenal goalkeeper Wilson believes that Arsene Wenger’s men may have to sacrifice their brand of attacking football in order to get a result against the Spanish side.
Wilson is quoted as saying by BT Sport: “I think Arsenal have to play like they did at Man City (in a 2-0 win) last season.
“It was an extraordinary tactical display, which is not always Arsene’s strength because he loves to play beautiful football.
“Ideally, Barcelona not scoring here would be great, no-one would put a penny on it but if you get nil against you, you think you can score away. It doesn’t need to be 3-2 or 4-3 going to the Nou Camp.”
Arsenal are currently third in the Premier League table heading into the final 12 games of the season. They travel to Manchester United next Sunday.
