Roma coach Rudi Garcia insists that his side must believe they can beat Barcelona in their Champions League clash at the Nou Camp.
The Serie A side are second in the group after four games, but five points behind pacesetters Barca.
Garcia has said his side “will be beaten” if they go to the Catalan capital with the intention of defending for 90 minutes against Luis Enrique’s troops.
“It is going to be difficult and we arrive with a lot of humility, but obviously we are not going to go out there already beaten,” said Garcia.
“If we want this to be a great game, then we have to score at least one goal. Obviously they are a side who win often, but they have lost some games in the league.”
Roma held Barcelona to a 1-1 draw in their opening game in September, the only points Barcelona have dropped in this campaign to date.
The La Liga champions needed late goals from Sergi Roberto and Luis Suarez to turn around their game against Bayer Leverkusen in the Nou Camp, while BATE Borisov were within striking distance until the final third of their game as they lost 3-0 in Spain.
“There is no such thing as an invincible side and that’s the beauty of football,” added Garcia. “When you think a result is already certain, football is one of the few sports where a weaker team can still win.”
Roma are 10.00 to win at Nou Camp, where the draw is 6.00. Barcelona are 1.29 for victory.
