Theo Walcott admits watching Barcelona pass the ball around Emirates Stadium was like a video game at times - but has warned the Champions League holders Arsenal will be the ones out to take control in the Nou Camp next week.
The Gunners survived a first-half onslaught by the tournament favourites, when Lionel Messi's men could have been out of sight, but for some brilliant goalkeeping by Manuel Almunia.
Arsenal trailed to a brace from Zlatan Ibrahimovic but hit back to draw, which gives them a fighting chance when they head to Spain.
However, Arsenal's courageous efforts came at a cost as captain Cesc Fabregas — who would have missed the return against his old club after collecting a booking — suffered what he has been confirmed as a broken leg in the penalty incident which had got the hosts level.
It could, though, have been much, much worse for Wenger's youngsters had Barcelona capitalised on their early dominance, when Arsenal were made to look ordinary and struggled to gain control of the ball.
Walcott watched the first half from the bench, before making a major impact on the match as his equaliser set up Arsenal's impressive finale. The 21-year-old forward accepts the Spanish giants are a class act, but sees no reason why Arsenal cannot get the result they need to progress next Tuesday night.
“In a way, as a young player growing up and still learning about the game, it was a fantastic experience just to watch some world-class players,” Walcott said. “It was like someone was holding them with a PS3 controller, controlling them all the time.
“It will be a very tough game there, but if we get an early goal and frustrate them then it will be a great game. We need to get the ball down and play, to frustrate them, like they did to us for the first 15 minutes especially when they kept the ball and created a lot of chances.”
