Notts County boss Ian McParland felt his side only had themselves to blame for their shock FA Cup second-round defeat by Havant & Waterlooville.
The Blue Square South side won 1-0 and McParland said: "What went wrong is what has been happening every week.
"Again we had somebody who defends lazily and tries to play offside. If that hadn't happened, they wouldn't have scored.
"We didn't play well at all and the performance was not acceptable."
