Boss Francis Vines will insist his Crawley side guard against complacency when they begin their bid for a trophy double in the West Midlands tonight.
The Sussex Senior Cup finalists are hot favourites to defeat premier division strugglers Halesowen in the two-legged Dr Martens League Cup final.
They have already beaten the Yeltz home and away in the league this season and Halesowen are embroiled in a battle to avoid relegation.
But Vines warned: "At this level you can play a team one week and win 3-0 and then play them again a week later and lose 3-0, anything can happen over the course of 90 minutes.
"I expect we are favourites, but I'm certainly not complacent and I will make sure that my players aren't either.
"We will go there and be as professional as we can be and hopefully get a result to take into the second leg."
Vines faces a selection poser after top scorer Nic McDonnell confirmed his fitness following a knee injury by scoring his 23rd goal of the season moments after coming on as substitute in Saturday's 3-3 draw at Newport County.
Fellow striker Warren Bagnall is also available giving Vines four fit strikers to choose from, all of whom will travel to the Grove.
Marc Pullan and Peter Fear are also in the squad after missing the weekend action but midfielder Neil Le Bihan has a bug and is doubtful.
Vines added: "We made a couple of individual mistakes which cost us two goals on Saturday when we were 3-1 up and looking as if we would score four or five.
"Hopefully we have got them out of our system. I want a clean sheet tonight and a couple of goals as well would be handsome."
Hastings United remain entrenched in the Dr Martens premier division relegation zone after stumbling to a 1-0 defeat at Chelmsford City last night.
Hastings never got going on a rock-hard pitch as they struggled to recapture the fine form shown in recent weeks.
The only goal of the game came on 14 minutes when a throughball bounced away from Tony Burt and Dale Watkins raced on to shoot past goalkeeper Dave King.
City looked the sharper of the teams from the start with Danny Slatter and Garry Cross forcing King into action at his near post.
Cross went close again with a volley before Brian Statham blasted over a penalty awarded for Stuart Playford's foul on Phil Dean.
Hastings struggled to create anything of note and the closest they came to scoring was in injury time when City survived a goalmouth scramble.
