The Bluebirds manager insisted his team can improve their level of football after their nervy 2-1 home victory over Stoke City.
But as exercise in repairing self-belief and restoring optimism for the remainder of the season, Bulut conceded the result was everything.
“When we had the last win at home, it was a long time ago. The confidence was not the best in the team because we lost games,” he said.
“I said after the last game (against Blackburn), ‘this is a game where we have to get our confidence back’. We got one point and this game was to continue to build on our confidence.
“It was a must today to get three points. I’m really satisfied with the performance of the team.
“Of course, you can add in parts of the game, better football, but in the situation we’re in right now, the first half was really good. We scored two goals, we got an early goal from a free-kick.
“We fought until the end to not concede a second goal.
