The Dons have picked up four successive clean sheets and head for a tough game on the south coast against in-form Southampton on Saturday.
"We will get the plaudits for it, but it's as a team. It starts from the front," he told BBC Three Counties Radio.
"If the strikers are working hard and stopping the other team playing it helps us at the back."
He added: "It's a false position [Southampton] are in. They started the season with a points deduction. They're on a great run as well, so it should be a good game."
