Garry Monk pointed to a lack of cutting edge as the Owls slumped to a fourth successive defeat at Wycombe on Saturday.
David Wheeler scored the only goal of the game seconds before the half time whistle and although Wednesday asked almost all of the questions after the break, the hosts held firm to take victory.
Monk said: “The players gave everything today, they worked and battled. It’s not running for us at the moment, we are missing that cutting edge.
“We’ve had all the possession in the second half but just couldn’t find that way through.
“I thought if we got one we’d have gone on to win the game. I couldn’t have asked anything more from the players but we are not getting the rub of the green at the moment.
“I take the responsibility, I have no problem with that. I will keep giving everything I have to get us out of this run of results. It’s not good enough for a club like Sheffield Wednesday.
“But we are together, the boys are together and you can see that with what has just been said in the changing room.”
