Dave Jones reflected on an afternoon of drama at Hillsborough on Saturday and said the Owls must capitalise on the highs and minimise the lows.
Wednesday drew 2-2 with Millwall and along the way conceded a last-gasp penalty that saw the Lions earn a share of the spoils.
But moving away from the whys and wherefores of the spot-kick award, Jones said the hosts only had themselves to blame for failing to post three points:
“It doesn’t matter if was a penalty or not, we have got the wrong side and haven’t recovered.
“You can’t do that at this level because you will be punished.
We had the highs in the game when we scored twice in the first half and we have finished the game on a real low.
“We have to make sure we see the game out, we have had the chances, and ultimately we have cost ourselves the points.”
Jones went on to stress there is no need for panic in the camp as the Owls await their first win of the 2013/14 campaign.
The manager reiterated the positives from the displays so far and added that Wednesday are not far away from making a significant impact.
He said: “In all honesty, we have done enough to get something from all of the games we have played so far.
“But we are not that far away and we will keep at it. It’s disappointing that we didn’t close the game because we are better than that.”
Jones added that Lewis Buxton was withdrawn at half time with a hamstring injury and will be assessed at Middlewood Road on Sunday morning.
