Mark Robins says his side are expecting a tough test as they head south to face Crawley Town in SkyBet League Two.
Mid-week results allowed City to stay above the dotted line, one point above Mansfield Town who face strugglers Chesterfield in tomorrow's early kick-off.
"After tomorrow we only one away day left. We are in a decent position and our destiny is very much in our hands," said Robins.
"We have got to try and capitalise when we have a chance. We have not done enough of that. Chesterfield face Mansfield tomorrow at one so we will know the result in that game before we play.
"For us though, it is about our performance and capitalising on the chances that come our way.
"The excitement starts to build now."
The Sky Blues now enter the final five games of the season sitting in seventh position, nine points behind the automatic promotion places and inside the play-off positions.
"I am expecting a tough game tomorrow. Crawley have had some mixed results but they try and play football the right way. Harry Kewell has not long finished a top-level playing career and he has his own feeling on his he wants to play the game.
"We have to try and stop them from doing what they want to do because they are at home. I want us to go and grasp the nettle tomorrow.
"It is all about individual decision making. Last week we conceded from a set piece, which can happen, and then we look and examine things like: 'Should we have put another player on the back post?', but that then brings everybody back and allows the opponents to get another ball into the area - and that gives them a second phase, which is what some teams are good at.
"Up the other end, we created some really good chances last week and the supporters were fantastic but we just did not do it well enough. Our quality isn't always on show and we just need to get that right."
He added: "It is all about these last few games now and we need to ensure that we are as close to the top three and if not inside the top three at the end of the season.
"We are not looking behind us. We are looking ahead. If the season ended now then we would be in the play-offs and we would have an excellent opportunity to get promoted back to SkyBet League One at the first time of asking."
