A superb strike by Matt Ritchie earned League Two Swindon Town their FA Cup second round victory over League One Colchester United.
Ashley Vincent crashed over for the U's after great work by Kayode Odejayi before Aden Flint's powerful header came back off the bar for the Robins.
Ronan Murray fired straight at home keeper Ben Williams as Swindon pressed.
Ritchie won the tie with a finely-struck drive from the edge of the area that flew in at the far post.
VIEWS FROM THE DRESSING ROOM
Colchester United manager John Ward told BBC Essex:
"I'm massively disappointed, the same as everybody else that supports Colchester United. We haven't performed as well as we'd like to.
"There's a shortage of confidence around the team, which is surprising. There was a little bit of edge about our game that was missing.
"Sometimes, if things are not quite the way they want, they get a little inhibited every now and again. I've seen it happen with bigger teams and bigger players than we've got here at Colchester."
Swindon Town manager Paolo di Canio told BBC Wiltshire:
"We deserve this victory. We deserved to win with a large number of goals.
"I want to give a chance to the fans and the club and go to Old Trafford or Stamford Bridge.
"Obviously I want to play against the best side possible."
