Manchester United boss Sir Alex Ferguson won't take away the spotkick duties from Wayne Rooney.

Ferguson was critical of Rooney for his miss last week against Bolton Wanderers.

But ahead of their clash at Arsenal, the Scot said: "If he wants to keep on taking them then he can, ­absolutely. It's down to him. I'd be happy for him to continue. If he's happy to take them, I'm happy to suffer! When he missed that one last week against Bolton it affected his game a wee bit. I think he can still improve. All players can improve."
