The Welsh side sit second from bottom in the Premier League and entertain West Brom in a relegation six-pointer on Saturday afternoon.
The Norwegian appears to be fighting a losing battle but Theophile-Catherine thinks the side are still more than capable of picking up the necessary points to survive.
He said: "If you look at our games, it's really been small details why we've lost.
"The other teams have just had that little bit extra. When Ole came in he told us that he wanted 'hard work' from us every day.
"I can now see it in everyone's face. I can see the motivation."
The full-back thinks that the high standards his manager set as a player will help Cardiff during the remainder of the season.
He added: "Ole has won many trophies as a player for Manchester United - and, even though I was little at the time, I remember him scoring in the Champions League final.
"They looked dead - but no one could ever rule out that United team. He drums that into us - that we have to work very hard to the very last kick of the match."
