Carlos Carvalhal reflected on what he called a second-half error that allowed Norwich to equalise and spur them on to take all three points against Wednesday at Carrow Road on Saturday.
Jordan Rhodes headed us in front in the first half but Marcus Maddison levelled matters early in the second half, then Timm Klose was left unmarked to head the Canaries in front on 68 minutes.
And when Barry Bannan fouled Harrison Reed in added time, Nelson Oliveira fired home the resulting penalty to make it 3-1.
Victory leaves the Owls 10 points from the play-offs and Carvalhal said: “The moment of the game was their first goal – that changed everything.
“When you are winning you should never get caught on the counter-attack but that is what happened. The players had shown a lot of quality in the first half but they compromised everything in that moment. As a manager it is not something you want to see.
The instructions at half-time were to stay solid and go looking for a second goal but we allowed them to score on the break and that was very disappointing.”
