Kilmarnock manager Kenny Shiels feels his players need more character to finish matches after losing 2-1 away to Inverness.
A late Graeme Shinnie strike gave Terry Butcher's side all three points in a dramatic encounter in the Highlands after Dean Shiels' superb equaliser.
"Over the five games we've played, we've only won one game," said Shiels.
"It's not good enough. We need to look at the character of our side and kill matches off."
Gregory Tade's 25th minute header put the hosts into a lead that lasted only 10 minutes before Shiels netted a fine solo effort.
However, Shinnie found the net in the 89th minute with a low strike and Inverness claimed their first win of the season, much to the Killie manager's dismay.
"I'm disappointed in the outcome of the game," said Shiels.
"I don't think we can have any complaints, because their attitude and commitment was better than ours and the players were pre-warned if we could match their spirit, we could win the game.
"For the first 25 minutes, we were second best, then we dominated for the next 50 minutes.
"They dominated the last 15 and capitalised on their domination, and we failed to do that.
"So, it's a fair result, a fair outcome."
Shiels was quick to point out the contribution of his son, Dean, whose fantastic solo strike levelled the match in the 35th minute.
"Dean is capable of doing that, and he looked a threat, but we didn't get the ball to him in the right way that we should have," said the Killie boss.
"We'll take a look at it on Monday and get to work on it to try and improve on our performance for the next game, but I don't like getting beaten, I'm like any other human being - when you lose a match, your emotions are in a poor state of mind.
"I feel very disappointed for the people who have travelled up today on a four hour journey from Kilmarnock.
"I really felt for them, because I wanted to put on a performance, entertain them and get a result.
"We didn't achieve that. We were in a winning position today at 1-1 and we didn't carry it out, from that position we should have gone on and won the game, and we didn't do that."
