Derry City will be without midfielder Nicky Low tonight as they bid to get back to winning ways when they face Bray Wanderers at the Brandywell.
The Candystripes have picked up just one point form their last four league games, the latest of which was a demoralising 5-2 defeat at the hands of St. Patrick's Athletic on Friday.
City's recent run of form began with defeat against tonight's opponents just over two weeks ago, and Shiels agreed that it was imperative for is team to get back to winning ways tonight.
"Everyone will say we have conceded four then five but we had a duck egg against Cork City last week and then everyone was saying how well we played," he said.
"Everyone was also saying how well we played against Dundalk because we tore them apart for half an hour but then we conceded a goal and then things shifted.
"So we have to address those problems and we'll come back again, you can be sure about that.
"We will have big spaces to play in and we're hopeful that we can get a result because it's important to our season that we get a result.
"If we win we're up in fourth which is good so it's about getting that result and getting us lifted."
Referee Ben Connolly played a significant part in Friday's game at St. Pat's by awarding the hosts a penalty just before half time, Shiels fears that his players are becoming paranoid over some match officials, which he is keen to avoid.
"We must go into this game not looking at referee's decisions and thinking 'Not him again'," Shiels continued.
"They were sort of expecting decisions which is unfair on the referee.
"The players have got to stop that and I have to use methods to stop that train of thought."
The Candystripes defeated Bray Wanderers 5-1 when the sides last met at the Brandywell back in March but fell to a 2-1 defeat at the Carlisle Grounds earlier this month.
