Midfielder Alex Oxlade-Chamberlain says the 8-2 defeat suffered by the Gunners at Old Trafford is still a talking point for the Arsenal players.
The Gunners were outclassed in all parts of the pitch and swept aside with ease by Sir Alex Ferguson's men back in 2011 and ahead of Monday's FA Cup game against the Red Devils, the Englishman will be hoping for a different outcome this time around.
"When we go there it's a tough environment," Oxlade-Chamberlain told the club's official website.
"The game we always speak about is the 8-2 but you can't go into those games with any doubt or any fear.
"I was at the premiere of the Invincibles documentary the other day and was listening to legends like Martin Keown and Thierry Henry talking about how they had no fear going into those games.
"They had no doubt they were going to get the right result. That's clearly the kind of attitude that you need to take into those big games.
"You have to believe in yourself, go there with no fear, be 100 per cent confident in yourself and go to get the result we are capable of getting."
