Boss thrilled with 2-0 victory
Manager Paul Buckle thought his side thoroughly deserved their FA Cup win at Cambridge which put the Town in the hat for Sunday's first round draw.
Goals from Andre Gray and Jon Shaw did the damage as the Hatters kept a second successive clean sheet.
And the boss was delighted with his team's performance at the Abbey Stadium.
"I'm absolutely thrilled," Buckle said afterwards. "I thought we controlled the game. When you come away from home you do expect to be put under pressure and Cambridge did that in the second half.
"However, we always looked dangerous on the counter attack and, had we scored the penalty, the game would have been beyond Cambridge. It could have been a lot more comfortable for us.
"Had Stuart scored, Cambridge would have had to have come out further and that would only have left more gaps for us to exploit."
Time and time again the Town got the better of their hosts by attacking down the flanks and Buckle was pleased that his tactics to exploit that space paid off.
"We knew Cambridge would set-up 433 and that left space down the wings," said the boss. "We told Stuart and Andre to keep disciplined because we knew we could get them in and it worked a treat. We got the tactics spot on.
"I could see the first goal coming. That was a great goal and the second was just fantastic. That's what we're all about: attacking at pace. We looked very dangerous.
"The only disappointing thing was that we didn't win by more but I'm delighted we're through because we all love the FA Cup and want to do well in it."
The biggest concern, however, for the Town was the first half injury to midfielder Alex Lawless who was stretchered off having collided with U's midfielder Ricky Wellard.
"He's got a sore ankle," confirmed Buckle. "It was a bad knock but we're hopeful that the nerves in his foot are all ok.
"At one stage it didn't look great but hopefully it's okay and it's just a bit of bruising."
