Leader Lionel Messi hopes that London's favorite attacking style of football will kill off the English club in the second leg of the Champions League round of 16.
The 'Gunners' won the first match at home 2-1, but on Tuesday they will face one of the strongest teams in Europe on their own field - the full "Camp Nou" stadium.
"We are sure that we will progress to the next stage," said the 23-year-old Argentine to "Mirrorfootball.co.uk". "Of course, we were very disappointed that we lost the first game because we created enough chances to win. But in Spain, everything will be different. I'm not sure that 'Arsenal' can defend, which will open the door for the London team."
"Barcelona" would have enough with a 1-0 victory, but that is not the goal of the Catalans, Messi assures.
"We are a team that always creates many opportunities. It is important to be precise and cold-blooded in front of the opponent's goal," he said. "The loss to Inter Milan last season will only motivate us even more. We are not even considering the possibility of being eliminated."
