Mike Williamson is confident Newcastle can rediscover their defensive resilience and continue pushing for European qualification.
The Magpies made a flying start to the season, conceding just eight times in their opening 11 games.
They have found the going tougher in 2012, with their back four having been breached 16 times in 10 league fixtures since the turn of the year.
A welcome clean sheet was collected in a 1-0 victory over Norwich, though, and Williamson is looking for the club to build on their first shut-out in six outings and cement their top-six standing.
"It's one of those, it's the unpredictability of football," the 28-year-old centre-half said on Newcastle's defensive displays.
"All you can do is prepare well and apply yourself 100 per cent.
"Of course it has been frustrating to concede goals, that's the main frustration for a defender, but I am sure it will turn around."
Williamson is looking to play his part in helping to keep things tight at the back, with his qualities complementing those of defensive partner Fabricio Coloccini.
The Argentine has built a reputation as a ball-playing centre-half, while Williamson is happy to be cast as the no-nonsense ball winner.
He said: "Colo does it and he is probably one of the calmest players I have ever played with in terms of coming out with the ball and his vision and his passing ability - he has got a lot in his armoury.
"Looking at players like David Luiz and people who try to come out, sometimes it can cause problems.
"But for me, I am just a straightforward English defender. I try to head it, kick it, keep clean sheets and let others play."
