Sebastian Larsson has admitted Sunderland need to shed their capacity to self-destruct if they are to avoid another scrap for Premier League survival.
The Black Cats headed into Tuesday night's home clash with travel-sick QPR at the Stadium of Light on the back of a four-game unbeaten run in all competitions, with head coach Gus Poyet believing they had turned a corner.
However, in the space of 46 soul-destroying minutes, they capitulated in alarming style to a side which had failed to collect anything at all from their previous 11 away games, and even a frenzied second-half fightback which did little to placate Poyet could not prevent them from slipping to a damaging 2-0 defeat.
The Uruguayan later insisted something fundamental had to change if they are going to shed their one step forward, two steps back approach, and midfielder Larsson mirrored his view. The Sweden international said: "You can never take anything for granted in this game and we've experienced that many times before. "I think the most frustrating thing is we felt like we were on the up, we felt like we were moving in the right direction.
"It's a game we shouldn't have lost, but we did, so we can only blame ourselves. It was down to us players on the pitch and we didn't do enough. "I've been here long enough to know that we tend to do these things at times, and we need to figure out why because it shouldn't keep happening."
