Mark Robins says his Sky Blues side want this season to be remembered for being a successful one rather than a negative.
"It is still in our hands," he said.
"There is everything still to play for. We have got the capability of finishing the job off.
"The next two aren't going to be easy. Gary Johnson is a really experienced manager and he will want to see this season out well. Every team we come up against raise their game and tomorrow will be no different to that.
"I am looking for a confident display. We have got some work to do and then we will just look forward to the game. We have nothing to fear."
The Sky Blues were beaten on Tuesday night against Lincoln City at the Ricoh after mistakes cost City a chance to all but ensure their place in the play-off places.
"I do not think we feared anything the other night. Our decision making was just poor. They put us under a lot of pressure and we did not deal with it very well. At this level, that is what you have to do.
"They were strong. They threw their bodies on the lines. We still created chances but we cannot keep chasing games like that.
"We were the masters of our own undoing.
"That is behind us now and all we can do is focus on the next two games."
City head to Whaddon Road hoping that they can contain Sudanese forward Mo Eisa. The 23-year-old has scored 22 goals so far this season after moving from Greenwich Borough in the summer.
"Eisa has done brilliantly well this season for Cheltenham. He is a threat. His movement is brilliant and he hits the target. He impressed me when we met at the Ricoh.
"You face these threats and we have to deal with them. That is the beauty of league football.
"Our support will come into play too. The fans have been magnificent all season.
"We have a brilliant support, we know that, and we want to send them home happy at the end of this season. We have got a great chance to get to a final at Wembley."
He added: "We have steadied the ship and we are going in the right direction.
"We have got players who can hurt anyone."
