Sunderland's lack of potency in attack is the reason behind their recent slump in form, says summer signing Sebastian Larsson.
The 26-year-old midfielder has been one of the Black Cats' leading lights, in an otherwise dismal start to the 2011-12 campaign - epitomised by the club's home defeat at the hands of fellow strugglers Wigan Athletic on Saturday.
A 2-1 defeat at the Stadium of Light leaves Sunderland in 16th place in the Barclays Premier League table, with just 11 points from 13 games played - a return that is simply not good enough for a club of its stature.
"We're just not good enough in the final third, let's be honest," Larsson told the Sunderland Echo. "No disrespect to Wigan, but we should be winning those types of games.
"We got off to the start we needed and the one we wanted to. We could have been two or three up after the opening 30 minutes.
"But that's been our problem all season - we don't take our chances. We don't put the game beyond doubt and we did the same thing again.
"They got a penalty and in the second half, it gets nervy and edgy. When we got down the sides of them, we weren't good enough."
A number of poor Sunderland displays has now heaped pressure on manager Steve Bruce, with some sections on Wearside calling for his departure. But Larsson is adamant that the club have the right man at the helm, and has urged critics to give Bruce time to turn things around.
"I still believe he's the right man for the job," the Swedish international added. "But I'm not surprised by how the fans reacted.
"We lost a game at home that we should have won if we want to get to where we want to be.
"We have to take a long look at ourselves and see why things are going the way they are. That's the Achilles heel, because we haven't conceded that many goals."
