Scarlets have no plans to allow Leigh Halfpenny to leave despite capturing Wales international Liam Williams.

Williams will return to Scarlets at the end of the season after his contract with Premiership champions Saracens expires.

However, Pro14 side Scarlets – who thrashed Ospreys 44-0 on Boxing Day – do not plan for Williams to replace his Wales team-mate Halfpenny, who can play at either wing or full-back, and whose deal runs out next year.

"We have got Liam and our intention is to have Leigh as well," said general manager of rugby Jon Daniels, in quotes reported by BBC Sport.

"That has been the message in our discussions with the Welsh Rugby Union around this. There is plenty of top-quality rugby in a season for two international players in the same position.

"If you look at teams who have historically been successful on a number of fronts over a number of years they have that strength in depth.

"That is our aspiration and what we are building here."

Scarlets will also be in need of a new head coach, with Brad Mooar returning to New Zealand at the end of the season to become part of Ian Foster's coaching staff.

Handre Pollard anticipates South Africa's Rugby World Cup semi-final with Wales will be settled by kicking, as he relishes the task of going up against Leigh Halfpenny and Dan Biggar.

Wales were dealt a blow on Thursday when Liam Williams was ruled out of the match due to injury, with Halfpenny coming in at full-back for Sunday's clash in Yokohama.

However, while the Six Nations champions have lost a key player in the form of Williams, Halfpenny is an expert kicker, while Biggar has also been in fine form with the boot.

Springboks' fly half Pollard has not had the same luck, converting 12 of his 19 attempts at goal, and acknowledged his own kicking must improve if Rassie Erasmus' side – who will be without influential wing Cheslin Kolbe – are to make it into the final.

"[Halfpenny] is a world-class goal-kicker, we all know that," Pollard said in a news conference.

"We all know it's going to probably come down to a kick or a drop goal. It's semi-final rugby, so you must try your best to be on target with every kick. If it's not to be, it's not to be."

South Africa defeated Wales in the 2015 quarter-finals, with Biggar a standout performer at Twickenham.

"We went at it four years ago, and I thought [Biggar] had a brilliant game that day. We really had to play well to win that match," Pollard added.

"He is a world-class player, unbelievably good. He is really not scared of the physical part of the match, and that's something that excites both of us. It's going to be fun to go against him for 80 minutes.

"[Wales] know what they are good at and focus on that. They are relentless in those areas. They starve you of possession and territory and enforce their kicking game on you. They take away your set-piece.

"It's not a gameplan or rugby with a lot of flair in it, but it's suffocating. If you fall into that trap, they will enforce their gameplan on you for 80 minutes and you will probably not win.

"It's going to be two sides tactically trying to figure each other out. We have a couple of plans up our sleeves."

Liam Williams' injury-enforced absence from the Rugby World Cup semi-final against South Africa is "a big loss" for Wales, but Warren Gatland does not think his team is any weaker.

An ankle injury sustained in an accidental collision during training ruled Williams out for the remainder of the tournament in Japan, with Leigh Halfpenny taking his place in the XV for Sunday's match in Yokohama.

However, Gatland stated Halfpenny had been close to earning a starting spot regardless and believes his experience will be an important boost for Wales.

"[Williams] is undoubtedly a big loss from an attacking perspective and what he has achieved in the game in the last year or so," said Gatland.

"But bringing in the experience of someone like Leigh Halfpenny gives us a different element.

"He is defensively probably the best full-back in the world in terms of his aerial game and coverage defensively.

"We had a long debate about whether we started Leigh in the first place and potentially move Liam to the wing.

"There was a long discussion about that so Leigh was probably unlucky he was not in the team in the first place.

"We are disappointed for a world-class player like Liam but we are happy bringing in someone with the experience of Leigh.

"It is a change but we don't think that we are weakening the side in any way with the changes we have made."

Jonathan Davies will start at centre after overcoming a knee injury and Gatland is pleased to have him available for the first time since the pool stage win over Fiji.

"We hope he is fit. He has come through training this week," said Gatland. "He was very close last week and he made a decision last week to rule himself out for the betterment of the team.

"Hopefully we can get through the rain today with the training and it won't affect us too much.

"We will have a shorter session this afternoon and we are excited where we are at the moment."

South Africa were dealt an injury blow of their own with livewire wing Cheslin Kolbe missing out after aggravating an ankle injury in the quarter-final success over Tokyo.

"Obviously he is a big loss to them with his ability to score tries and his footwork," Gatland said of Kolbe, for whom Sbu Nkosi will deputise.

"We were probably going to target him aerially anyway. You talk about their kicking game, I think our kicking game has to be good as well. They definitely have a bit of pace in the back three.

"At this stage of the tournament, you are always going to lose a couple of quality players, and in them losing Kolbe and us losing Liam Williams, it's probably one each in terms of that."
