Bury caretaker boss Peter Shirtliff described his side's performance in a 4-1 defeat against MK Dons as the worst in his time at the club.
Dean Bowditch scored a hat-trick and Luke Chadwick added another in a miserable final game in charge for Shirtliff. Sitting winless at the bottom of League One, Bury are set to appoint a permament boss before next week's trip to Stevenage.
"It's disappointing because that's the worst performance since I've been here, both as a coach and as manager," said Shirtliff. "They're a very good side but we didn't do ourselves justice. The club are now looking to appoint a manager and that's not me, but I want to stay at the club because I enjoy it here."
He added: "They're not good enough to get us out of this position based on that performance but they're better than that.
"We played against a very good side who played well, but there's a saying that you can only play as well as the opposition allow you and we let them play well."
Milton Keynes took the lead when Chadwick rifled a cross in from the left and Bowditch slammed a no-nonsense finish past Trevor Carson.
The Dons striker then pounced again in the 55th minute after Carson had denied both Ryan Lowe and Chadwick. Bowditch completed his hat-trick with a cool finish after latching on to a clever free-kick from Stephen Gleeson.
Bury claimed a consolation when substitute Lenell John-Lewis lobbed the onrushing David Martin before Chadwick slotted home in injury time.
Dons boss Karl Robinson said: "It was our most complete performance this season."
He added: "All the goals were very good and we defended well, although I'm disappointed with the goal."
