Karl Robinson was delighted to see his side pick up their first win in three matches on Tuesday night, but was left to rue chances missed to make it more comfortable.
Dean Bowditch scored the only goal of the game after 29 minutes in the 1-0 win over Charlton Athletic at stadium:mk, but it should have been a far greater margin of victory.
And with unbeaten Brighton up next, Robinson knows his side will have to be more killer in front of goal if they are to get anything from the Amex on Saturday.
“I thought we were outstanding,” said the manager. “But missing the chances didn’t cost us. I’m disappointed in that sense, but we should have had three of four. And when you create that many chances, you’ve got to take them.
“Nicky had the best chance, but we should have been out of sight. Darren Potter had one, Bowditch had one, Church had one, Diego Poyet, Samir Carruthers - but it wasn’t to be.
“They’ll click - they’ve got to. We’re getting a lot of practice!”
After a good performance went unrewarded against Hull last Saturday, Dons put in more leg work on Tuesday night as they dominated proceedings against lowly Charlton.
With four minutes added on in the first half and eight in the second, Robinson’s charges looked out on their feet come the final whistle.
But the win sees Dons move further away from the relegation zone, albeit still in 20th in the table.
Robinson said: “It takes us four clear of the drop zone, which is a nice cushion to have. I’d like to sustain that. It’s a tremendous win.
“When the whistle went, it was like a scene from Platoon: everyone hit the ground. It shows the effort we put in. They’re exhausted. We’ve got to pick ourselves up and go again on Saturday.
“We took a lot of big risks today, and it was one of the biggest games of my career.
“Not winning today would have made the Brighton trip even more difficult.
“It’s important we keep our distance from that relegation zone now, especially before the international break.
“There are four or five with a similar tally. It’s important that we move on and up.”
