Marcus Rashford played a key role off the bench as Manchester United avoided a shock defeat at Sixfields.
Manchester United ended a three-game losing run with a 3-1 triumph over Northampton Town in a third-round EFL Cup tie played out in front of a record crowd of 7,798 at Sixfields.
Having warmed up in a hotel car park before the tie, Jose Mourinho's side needed second-half goals from Ander Herrera and Marcus Rashford to book their place in the last 16.
Michael Carrick's first-time finish from the edge of the area in the 17th minute had put United ahead, but some shoddy defending allowed Northampton to equalise at the end of the first half.
