Paul Gustard has called on Harlequins to bounce back from their loss to Clermont Auvergne ahead of their Heineken Champions Cup tie with Premiership rivals Bath.

Quins crashed to a 53-21 defeat away to the French side in the opening match of their European campaign last weekend.

The result means they sit bottom of Pool 3 ahead of Round 2 and have plenty of ground to make up if they want to reach the quarter-finals for the first time since 2012-13.

But head of rugby Gustard believes his side are well placed to revive their chances against familiar foes after last week’s disappointment.

“We have had a good week training and put the result from last week behind us,” he said.

“The boys have shown great character and togetherness and are looking forward to playing as we welcome Champions Cup rugby back to the Stoop.

"We have mixed up our training week and changed a few things around which has been aided by the return of big Sink [Kyle Sinckler] and Joe Marler.

"They are two big personalities whom are both well-loved at the club, and it's great to see them around the facility once more.

“We know Saturday represent an opportunity to put our learnings into practice against a strong Bath team and put together a performance we can be proud of.”

Prop Sinckler is unavailable for the game itself but along with Marler, Gustard also welcomes back scrum-half Danny Care from injury and Italian international Michele Campagnaro makes his first start for the club at outside centre.

Academy player George Head has been confirmed on the bench and could make his debut, while Semi Kunatani and Paul Lasike may also feature for the first time this season.

In the run up to the clash, Quins confirmed on Thursday they have appointed former Bath coach Toby Booth as an assistant to Gustard and his team.

Having left his position as Bath first-team coach in June, he reunites with Quins captain Chris Robshaw following their time together with England Saxons.

Booth, 49, has signed on for the remainder of the season and Gustard believes his experience will prove invaluable.

He said: “I have known Toby personally for a long time and he is a coach who will add tremendous value to our whole group.

“He has a successful record of developing players and teams and we cannot wait for him to start.

“His main remit will be our lineout but I know he will have a significant impact on the wider programme and will prove to be an outstanding resource for not only myself but our young and talented coaching group.

“He is a great guy with good values and someone who had a big impact on my personal coaching pedagogy early in my career.

“His signing is a great boost for the club and we look forward to seeing the impact he will quickly make.”
