Mike Williamson believes that Newcastle's clash against QPR could be one of their biggest of the season, with early-season disappointment for Alan Pardew's side leaving them 15th in the Premier League table.
QPR come into the game following their first win of the season, but most importantly they have not lost under new manager Harry Redknapp, and have closed the gap between themselves and Newcastle to only seven points.
Because of this, Wiliamson understands the pressure which Newcastle are under to get a win against QPR, and extend the gap to 10 points again, while improving their record of only two wins in their last 10 Premier League games.
Williamson told the Daily Mail: "We've had a lot of big games and QPR is right up there with the most important. The lads know that and we're solely focused on getting the win.
"It's a must-win for us and we go into every game with that mindset, but with Manchester United and Arsenal coming up, it's even more so.
"Last season, everyone was coming up and patting us on the back. Now they are asking us what's gone wrong.
"This is such a passionate city. They deserve to see a few more better displays. We are all working hard to try to put things right and give the fans something to cheer."
However, the squads of both clubs have been exposed by injuries as lacking depth, with QPR struggling to cover the absence of Bobby Zamora and Julio Cesar, and Newcastle manager Alan Pardew having to cope without Johan Cabaye and Hatem Ben Arfa.
