Harlequins coach Nick Evans warned that we are yet to see a full power Quins side ahead of Friday's clash with Gloucester.

Tabai Matson's team welcome the Cherry & Whites to the Stoop tomorrow for a high-stakes battle, with Quins sitting just one point ahead of their opponents in the table.

Both teams will be boosted by the return of key international players as Matson named Tommy Allan and Andre Esterhuizen in his starting line-up, whilst Gloucester can call on fly-half Santiago Carreras and Louis Rees-Zammit on the wing.

And attack and backs coach Evans has teased that there is more to Quins than we have seen so far.

He said: "We're all excited to get back into league action under some Friday Night Lights. For a number of reasons, we haven’t fired on all cylinders yet this season.

"In all parts of our game we've had fleeting moments, we've attacked and defended well in some areas but we’re still looking for that complete performance.

"It's something over this last period that we've really dug in to; around what that looks like and how we can replicate it this week."

Harlequins scraped a narrow 26-24 victory over London Irish in Round 8 of the Gallagher Premiership, with a last-gasp try from George Head making the difference.

On the other side, the Cherry & Whites will look to bounce back to winning ways following a 27-21 defeat to Newcastle Falcons last time out.

"I expect a reaction from Gloucester following their defeat to Newcastle," said Evans.

"We've spoken about that and about how they’ll be hurting from that result.

"We expect they'll bring the Gloucester way of playing to us and there will be a huge set-piece focus on what they do. They have a good kicking game too.

"It's certainly a challenge this week that we’re looking forward to."
