HOOKER Jack Singleton admits Sale Sharks’ “air of unpredictability” makes them a real threat to Worcester Warriors tonight (7.45pm).

While a resurgent Warriors side will be looking to extend their winning run, Sale will arrive at Sixways desperate to put further breathing space between themselves and the bottom two in the Aviva Premiership.

Worcester have been scoring tries for fun of late with fit-again duo Ryan Mills and Francois Hougaard pulling the strings.

But Singleton was keen to highlight the “X-Factor” players Sale possessed, including England wing Denny Solomona, Australia ace James O’Connor and South Africa star Faf de Klerk.

“They will be physical,” Singleton said.

“Their pack is very good with a strong driving maul and have got some X-Factor backs.

“They are a well-drilled team and we have got to be on our A team to deal with them at home.

“Every game is different and you don’t really know what Sale are going to bring so we can’t reminisce about the last two weeks and not turn up.

“Players like O’Connor, Solomona and de Klerk all have flair and are brilliant at what they do so they do have that air of unpredictability.

“It will be tough to deal with, but hopefully we will be on form.

“If we could go two points behind Sale and with the other clubs not too far ahead of them it would be massive boost for our confidence.”

Warriors ended their 20-month wait for an away league victory last weekend when they defeated Leicester Tigers 31-27.

It was also Worcester’s win ever win at Welford Road and Singleton said it was a monkey off their back as they bid to keep climbing the table.

“I have not won away in the Premiership since I have been here so it is new for me and for the club as we had never won at Welford Road,” Singleton said.

“It was a special changing room after and one I will remember for a long time.

“We spoke about it a lot at the start of the season being able to travel well because last year we did not win away.

“So I think it is a monkey off our back and having a lot of the boys back fit definitely helps, so I am looking forward to facing Sale.

"The leadership of Mills has been massive as well and Francois is a great player as well.

"Our attack has been flowing and I think they have been a key to that."

“We are trying to look up the table rather than behind us and we just want to keep climbing.”
