Dave Penney hailed Oldham's best performance of the season after MK Dons were beaten 2-1 at Boundary Park and condemned to their first away defeat of the season in League One.
Alan Sheehan and Keigan Parker struck high-class goals as Penney's Latics side completed a hat-trick of league wins.
The Oldham boss said: "When you play so well you hope you will go on to achieve the right result so I'm delighted."
He added: "We battled away, our work ethic and tempo were excellent from the first minute and both goals were fantastic.
"It's nice to have three straight wins and there is a spring in our step at the moment, although confidence has never been an issue.
"MK Dons are a big, strong unit who are dangerous on set pieces, but we defended well even though we made it a bit difficult at the end."
