David McGoldrick scored a hat-trick as Derby moved into the play-off places with a 4-0 thumping of Forest Green at Pride Park. McGoldrick notched his treble, capped with an 87th-minute effort, after Nathaniel Mendez-Laing had put the Rams ahead five minutes into the contest.
MK Dons won in their first league match since sacking boss Liam Manning, triumphing 2-0 at Portsmouth. Bradley Johnson and Jack Tucker got the goals as the Dons, under Dean Lewington’s interim management, moved up a place to 22nd, swapping spots with Burton.
