Lions v Western Force live: Result and reaction as impressive tourists run rampant in Perth

The British and Irish Lions claimed their first victory on Australian soil by overwhelming Western Force 54-7, but a possible injury crisis is brewing at scrum half after Tomos Williams was forced off.

Williams was among the Lions’ star performers at Optus Stadium but his match was over when he injured his left hamstring during the act of finishing his second try in the 47th minute.

The Wales half-back limped from the pitch to leave the Lions sweating on his fitness given Jamison Gibson-Park has yet to play on tour because of a glute problem, potentially leaving Alex Mitchell as the only available option in the position.

It was the biggest disappointment of a mixed evening for Andy Farrell’s men, who bounced back from their 28-24 defeat by Argentina with an eight-try demolition of the weakest of Australia’s Super Rugby franchises while exposing areas of concern.

Head coach Andy Farrell has given his initial thoughts on the performance and singled out winger Mack Hansen as doing good stuff.

Speaking to Sky Sports, Farrell said: “Again, a new-ish team. Plenty of learning from last week and the same again from this week.

"When we get out composure in the second half we was able be nice and calm.

"I mean, let's be honest, the Force took it to us. I thought they played a tough high-percentage game. They kept the ball really well and we kept them in good field pos through our ill discipline.

"It was a real good test for us in that first half glad how we composed ourselves at half-time and kept our composure throughout the second half.

"It is nice to get tries on the board and a few good individual performances. That is all good for the future, and we have to keep pushing one another.

"If you want to look what a Lion should do for his team-mates is when Mack Hansen went up and down the field and fought for his team-mates. That's the sort of spirit we want."

On Tomos Williams injury: "Tight hamstring. You don't know what these things are like. We will assess that."

Former Exeter Chief and Australia international Nic White skippered Western Force and scored their only try.

He picked out Henry Pollock as someone who impressed for the Lions.

Speaking to Sky Sports, White said: “Towards the end, the Lions were able to stay at that intensity longer than us, as expected with four international sides together.

"We thought we put them under pressure but just couldn't take some of the opportunities we had. We certainly enjoyed it a lot. We are disappointed it fell away a bit at the end but that is what a quality Lions side can do.

"Henry Pollock certainly lived up to the hype. From 50 minutes plus they kept the intensity and he came into his own. It was so exciting for our guys to go up against them and in front of a record crowd it was unbelievable.

"There were some moments we were quite happy with but they showed their class. We did ourselves proud in the first 40-50 minutes and we will enjoy it now, we will share a jersey and a beer with them. What a way to start the tour."

Lions skipper Dan Sheehan was impressive and discussed his first game in a Lions shirt, as well as the improvements needed

Sheehan, speaking to Sky Sports, said: “It was a really special day for me and a lot of other lads.

“Something special and something you watch growing up and wanting to be in this jersey. Happy with that result, but there is plenty for us to work on. We started really well, but our discipline let them back in.

"We were inaccurate with their restarts. We are still getting used to each other and those new combinations.

"From here on in, it is coming thick and fast. Every team we come up against will be hungrier than ever."

Joe McCarthy was named as player of the match for the Lions and the Irish lock has reflected on blowing off the cobwebs.

McCarthy, speaking to Sky Sports, said: "It was tough. A lot of kicking, Australians like to play ball and play quickly. It was great fun.

"We felt like we had them, and they came back hard and a bit of discipline let them back into it - we will get better with it.

"We want to be a ruthless side but there’s plenty more to improve on.

"I think I blew the cobwebs off - I should be flying through the tour now."

A job well done in the end by the Lions. Some work-ons as ever (hello restarts...) but they’re building into the tour nicely

The injury to Tomos Williams will be a concern, though - it looked like a hamstring for the Wales nine. We await updates on the severity of the issue and hope that he pulls up ok.

A mixed bag from the Lions in the first half, moments of magic interspersed with some ill discipline and some surprisingly sloppy territorial play - but their attack really clicked at times in the second, with yet more signs of what the coaching staff are trying to develop in terms of ball movement. The first win of the tour, of course, and a decent enough way to bounce back from defeat in Dublin.

They do! The Lions raise the bat as they hit 50 with the final play, Alex Mitchell scoring after Sione Tuipulotu and Mack Hansen had created a break.

The conversion is there from Marcus Smith and that’ll be that.
