Head of rugby Paul Gustard reckons his Harlequins side will need to produce a “complete squad performance” against Exeter Chiefs to secure their place in the Premiership Rugby Cup final.

Quins will continue their bid for silverware on Sunday (1pm) when they face Chiefs at Sandy Park.

It is the second time Quins have been in the last four of a competition in the past 12 months having lost at Clermont Auvergne in last season’s European Challenge Cup semi-final.

But Gustard is determined to go one step further as the London club look to defeat Exeter who won the Premiership Rugby Cup, formerly known as the Anglo-Welsh Cup, in 2014 and 2018.

“Exeter are currently the pre-eminent side in the domestic game,” Gustard said.

“They possess real quality amongst their squad allied to strong tactical capacity, so to progress to the final we need to put our best foot forward.

“In the past 12 months we’ve seen the club in two semi-finals and we want to continue putting ourselves in these positions to compete for silverware.

“The next step of course is to make a final which will require a complete squad performance on Sunday."

Gustard has made only one change to the starting XV that thumped Saracens 41-14 at The Twickenham Stoop in the Gallagher Premiership last weekend.

Hooker Elia Elia picked up an injury which will ruled him out of action for several weeks with academy player Jack Musk starting in his place.

With props Joe Marler and Kyle Sinckler away with England for the Guinness Six Nations, Musk will play alongside Santiago Garcia Botta and Will Collier in the front row.

Stephan Lewies and Matt Symons will combine at lock while James Chisholm, captain Chris Robshaw and Alex Dombrandt make up the back row.

In the back division, Aaron Morris keeps his place at full-back with Cadan Murley and Gabriel Ibitoye on the wings.

Danny Care and Marcus Smith will continue their half-back partnership while Paul Lasike and Tom Penny link up in midfield.

“Last weekend against Saracens we demonstrated exactly how threatening Harlequins can be both sides of the ball,” Gustard said.

“It was a positive all-around performance that we can be proud of, but it was of course disappointing to lose ‘Eazy’ (Elia Elia) who is enjoying a breakthrough season.

“Injury presents opportunity for other players in the squad and we’ve shown resilience and strength in adversity, which is a huge tribute to the foundations we are building.

“We are a united group and it’s a great environment to be around as players and as coaches.”
