The Wanted are on course to score their third Official UK Singles Chart No.1 with new track Lightning.
Max, Tom, Jay, Siva and Nathan look likely to knock Rihanna and Calvin Harris' We Found Love from the top spot after two weeks, fighting off some tough competition from Kelly Clarkson and Lana Del Rey, who both have new entries in the chart.
The lads have previously reached the summit with debut single All Time Low and summer dance anthem, Glad You Came, earlier this year.
Elsewhere in the Official UK Album Chart, former Oasis star Noel Gallagher is on track to hit No.1, after going head-to-head with 2010 X Factor champ, Matt Cardle's debut LP, Letters.
After failing to score a chart-topping single with Run For You Life, it seems Cardle will now have to settle for No.2 in the album chart behind Noel Gallagher's High Flying Birds.
Steps: The Ultimate Collection, Adele's 21 and Ed Sheeran's + complete the top five, while Katy Perry's California Dream record is on course to climb the countdown from No.27 to sixth place.
Chris O'Donnell is set to score this week's third highest new entry with his Ultimate Collection, while James Morrison, Bruno Mars and Evanescence all feature in the top ten.
