After Cardiff completed the archetype smash and grab, Danny Röhl vented his frustration as the Owls went down 2-1.
Wednesday bossed the lion's share of the contest but left empty handed after a late double blow from the Bluebirds.
He told swfc.co.uk: “This is a frustrating moment for me because we controlled the game and should have won the game.
“It’s a hard one to take but this is football and we have to move forward, it is only one game.
“It is very frustrating because of the other results but this is the Championship, last week we were celebrating two late goals of our own and this week we are frustrated by two goals to the opponent.
“We have been very unlucky today but we have a lot of games to look forward to over this period and we will not be down.
“The players are frustrated and disappointed but the next game is not far away and we will be ready.”
