Garry Monk said Wednesday will learn from their 2-1 defeat to Blackburn at Ewood Park after two late goals cost the Owls dearly after taking the lead with six minutes to go.
Substitute Jacob Murphy scored his second goal in Wednesday colours to put the visitors in front but strikes from Tosin Adarabioyo and John Buckley earned an unlikely win for Rovers.
Monk said: “It was a tough one to take today. We came up against everything we expected in the build-up to the game.
“We knew it would be a tough test, but we did well for majority of the game and earned the lead.
“From that position we shouldn’t have lost the game, but individual errors and a lack of concentration have cost us the win.
“These things happen in football, but we know we can learn from this and make sure that it doesn’t happen again.
“It hurts because we knew exactly what kind of game to expect. We knew it would be tight for an hour before opening up and the substitutions worked well.
“We got into the lead and it looked as though the points were ours but a lack of concentration has cost us.
“It’s very uncharacteristic of us, it’s the first time I’ve seen it, but we have to learn from it, dust ourselves down and be ready for Swansea next Saturday.”
