Pre-season ambitions of a play-off challenge have faded after a promising start while there was no repeat of last term's FA Cup exploits, and although 21 games remain in the National League, the prospects of making up a 12 point deficit on the top five look slim.
A victory at Telford, where Sharps finished last season, on Saturday (3pm) would provide the Blues with a much needed confidence boost, £5,000 prize money and give them something to hold onto heading into 2016.
Sharps said: "Everyone that's in the draw right now will be thinking about Wembley and thinking it could be them this year and we're no different.
"It will be a tough test against Telford but for a club of our size it's the most realistic trophy we can win and that's what we'll be going to do.
"We'll take it one step at a time but it's a competition we're very keen to do well in."
Sharps, who lives about half an hour outside Telford, is looking forward to returning to New Bucks Head.
The 35-year-old made 15 appearances on loan to the Bucks at the end of the 2014-15 campaign, but could not prevent them being relegated despite a significant upturn in form after his arrival.
Telford have continued to struggle and sacked manager Steve Kittrick five games into the new season. Rob Smith returned for his second spell in charge but has been unable to lift the club off the bottom of National League North.
Sharps said: "Although we didn't succeed in trying to stay up last season, I had a good time there and we played to the end and I think we won four out of the last five games.
"It was touch and go whether I signed there this season but luckily for me I signed for Chester in the end. It will be nice to go back and see some old faces. I know there's been quite a few changes there but some of the old faces behind the scenes are still there."
Sharps is competing with Ben Heneghan, available again after suspension, and on-loan Alex Whitmore for a starting berth against his former club.
Sharps struggles to explain the drop off in results after such a bright opening to the season but insists it can be put right if everyone works together.
He said: "Our individual performances need to pick up and then as a team collectively we should improve. I think performances have been there in fits and starts in games but we need to do that consistently and not for 10 or 15 minutes.
"If we knew what was behind it then we'd put it right straightaway. It's a difficult one and I'm sure the gaffer and Macca are thinking long and hard about it.
"We need to repeat what we did earlier in the season. We've still got good players, we're still a good team but we need to get that confidence going and get back on track."
