Two goals from Matt Ritchie helped Swindon to their biggest victory of the season as they thrashed Barnet.
Raffaele De Vita put the Robins ahead, collecting a pass from Alan Connell and shooting powerfully past Dean Brill.
Ritchie grabbed his first when he pounced on a rebound after his first shot had hit the bar before Mehdi Kerrouche's header put Swindon 3-0 up.
Barnet's Mark Byrne had a shot pushed over by Phil Smith, but Ritchie completed the rout with a low finish.
VIEWS FROM THE DRESSING ROOM
Swindon Town manager Paolo di Canio told BBC Wiltshire:
"I didn't have any doubts about my team.
"To win 4-0 is a fantastic result but obviously we deserved it because we played very well today.
"Matt Ritchie is at different level - his delivery is a different class and the way he worked off the ball was crucial."
