Newcastle United defender Mike Williamson believes that "hard work" will be key to the club turning around their current form.

The Magpies have not won in their last four Premier League outings, collecting just two points in the process.

However, Williamson is adamant that there is enough quality in the squad to reverse their current fortunes.

"People are going to look at that and, by the standards the boys have set earlier on in the season, they are going to start calling it a mini-crisis and things like that," said the centre-back. "But I just think in the last three or four games, the luck just hasn't been on our side.

"We have worked hard, we have put as much preparation and heart into the games and we just haven't had the rub of the green, with the other night and the penalty against Sunderland, 2-0 up against Wolves, things like that.

"We just haven't had that luck, but the lads have been working hard - that's what can turn it around, hard work, and that's what we have got in that dressing room."

Williamson joined Newcastle in 2010 from Portsmouth.
