Arsenal boss Arsene Wenger believes indiscipline will not be a factor for his team when they clash with Manchester United on Sunday. Meetings between the two sides have been bad tempered in the past and the Gunners go into the game with Alex Song, Gervinho and Emmanuel Frimpong suspended.
Wenger said: "The discipline has cost us a lot since the start of the season. If we had mastered our responses and reactions we could have six points.
"It's even more important to get results and not let Manchester United away too early. It is vital for us to have a good game on Sunday.
"Sometimes at the beginning of the season it is like a Western film, they (the players) come out stronger.
"But we have shown that we have mental strength and good unity to fight. I'm confident we will be solid on Sunday and have a big performance."
