Warrington coach Tony Smith says his side cannot afford to underestimate London Broncos on Saturday.

The Wire have won all three of their fixtures in The Qualifiers so far, while London have just one point to show from their three games.

However, Warrington made a slow start against Halifax last time out as they were tied at 4-4 at the break before going on to record a 22-8 win.

Smith also feels the Broncos are unlucky not to have more points on the board after close encounters with both Catalans and Hull KR, and he has warned his squad against complacency ahead of their trip to London.

"London have been very competitive," Smith said, as reported by Rugby-League.com. "They are a bit unlucky to have only one point. They are a difficult team to play with experienced players in ranks.

"It's their home pitch and we are prepared for that. We are still looking to build so will roll our sleeves up and take on the job in hand.

"With Championship sides, you don't recognise as many players so it's a little bit of the unknown. They also have a more openness in style, they're willing to take risks.

"We're three from three but we don't want to get complacent as we've still got work to do. The first couple of games were good but in our last outing the first half was a bit off."
