Stormers' inaccuracy a concern for Fleck
The Cape side outscored their opponents two tries to one, but were frustrated for most of the game by a dogged Cheetahs outfit.
"Overall we were not happy with our performance," said Fleck.
"As good as we were last week, we not as accurate as we should have been.
"Credit must be given to the Cheetahs – they got under our skin for the first 60 minutes, but we are pleased with the end result and pleased with the last 20 minutes."
Fleck was particularly disappointed that his pack could not assert their dominance on the game like they did against the Bulls last week.
"Our pack didn't play as well as it should have. They played really well against the Bulls, but were slow to react today.
"Our first-half set piece was not good enough and credit to Lood [Lodewyk de Jager] and the Cheetahs.
"Too much loose ball was being thrown around and our line-out did not operate the way it should have. There was a fair contest in the scrums in the first half and again credit to the Cheetahs for that. In the second half we just felt the ascendancy was coming our way and it was just a matter of having patience and we did not have that in that first 60 minutes.
"It was a frustrating performance. We were not accurate and credit to the Cheetahs for getting between us and forcing us to make those errors."
Stormers co-captain Juan de Jongh said the backline was not up to scratch either.
"Our back play had a lot of mistakes, but those are things we can rectify when we play the next game," said de Jongh
"The guys did well to grind out the win because it was a tough day at the office for us. We had a lot of ball and we just could not capitalise and finish off those opportunities. There are still things we need to work on for the Sharks game."
Flyhalf Robert du Preez is the major injury concern for the Stormers ahead of that game with the Sharks at Newlands next week. The 22-year-old limped off with a knee injury in the second half.
Fleck said he did not know the extent of the injury.
