The United manager admitted he had done extra homework on the Blue Square Premier leaders such is the importance of a cup run to the club and the chance to boost its finances. And he also plans to get his squad together to stay in a hotel tonight to make sure his players, many of who travel from well outside of Cambridge, are well rested. Quinn said: "We've analysed Aldershot more than I would have done for a league game because it's such a massive match.
"I watched them last Friday against Weymouth and saw some weaknesses, so I just want the lads to know what they're up against right down to the finest detail."
Quinn was confident United could see off the Shots despite being held to a 1-1 draw at home by the Hampshire side in September.
He said: "We should have killed them off in the first half in that game, but Aldershot came back and showed a lot of resilience in the second half.
"Gary Waddock has brought young, quick, strong players into the team and they've got the confidence that they feel they can beat anybody.
"They've got a lot of pace so it will be a good test for our defenders, and we've got to show a lot of character.
"Aldershot will come here knowing they're in for a tough ride and we've got to make sure we take the game to them.
"I've told the lads we've got to be in the hat at the end of the game."
Quinn is likely to stick with an unchanged line-up for the third game in a row, although there is a distant chance Danny Potter could be fit to return in goal following a finger injury.
United (probable): McShane, Morrison, Peters, Albrighton, Gleeson, Wolleaston, Reed, Pitt, Knights, Rendell, Boylan.
Aldershot (probable): Bull, Gier, Straker, Davies, Day, Newman, Soares, Chalmers, Dixon, Elvins, Harding.Source: http://www.cambridge-news.co.uk/
