Daniel Farke says Norwich City went close to taking far more than they did from Leeds United, following Saturday's 1-0 defeat at Elland Road.
Pontus Jansson's header late in the first half proved enough to give the hosts victory in the Sky Bet Championship, despite a strong performance from the Canaries.
"It was a very close game," Farke told Norwich City TV.
"We gave away too many set-pieces, which we'd spoken a lot about. They were able to score from that and it determined the game.
The City chief says his squad are closing in on reaching the levels they hit earlier in the season, and are short only of the finishing touches at present.
"We created a lot but at this level you have to use your chances," he added.
"If you don't do that, you have to have a clean sheet to get a point. We weren't able to do this and that's the reason we lost.
"It's disappointing but it's not the day to accuse. The performance was good and I have to give my lads trust and confidence.
"Our performances are much better than they were in our tough run. We are creating a lot more.
"We are really close to a new positive run. All the games are close and it's about the last four or five per cent."
