Wales and British & Irish Lions back Williams is a firm favourite down west.
The 26-year-old was a scaffolder playing club rugby for Waunarlwydd and Llanelli until 2011 when he made his breakthrough with the Scarlets. The rest, as they say, is history.
Williams believes a PRO12 title success, which would represent Scarlets’ first silverware since 2004, would be the perfect way for him to bow out before joining Saracens for the start of next season.
He said: “I don’t want to count my eggs before they’ve hatched, but to lift the trophy would mean the world to me. I’ve been here for six years and the final is going to be huge.
“When we beat the Ospreys to seal our place in the top four, I said to the boys we need to focus because now we’ve got two more big games. If we actually go out there and win the PRO12, it couldn’t get any better for me. Six years is a long, long time and I’m excited for the game.
“I’m sure the whole of the squad is as well. We’re looking forward to the challenge ahead.”
Scarlets and Williams face Munster at the Aviva Stadium full of confidence.
Wayne Pivac’s team became the first to win a PRO12 semi-final away from home last weekend when they beat Leinster 27-15 at the RDS despite losing Steffan Evans to a red card just before half time.
The fact Evans is available for the final after his sending off was rescinded, plus Scarlets’ win over Munster at Thomond Park in February, are further plusses for Pivac’s men.
“In the past couple of weeks we have beaten Ospreys at home and we’ve just been to Leinster and beaten them as well,” Williams added.
“Last weekend every single part of our game was outstanding. We’ve been back in this week and the energy is up. The mood is really good and all the boys are enjoying a laugh and a joke.
“I think it will be a great atmosphere in the Aviva Stadium. There is nothing better than having the crowd being really loud. It spurs us on. I just can’t wait to get out there now and face Munster.”
Williams, who has 43 Wales caps to his name and will face New Zealand with the Lions next month, is no elder statesman. But one of the most popular players in Scarlets’ history has already helped to bring through fresh faces. Evans, his back three colleague, is a good example.
“We’ve got a lot of young players coming through now and this is where we want to be,” Williams said.
“Hopefully in the next couple of years – even though I am leaving – the boys keep it up. The young guys speak to me and my door is always open for those boys to come and have a chat.
“If they want to do any extras with me, or just have a chat about life as well as rugby, then I’m always there for them. It will always be like that.
“There’s nothing better than having the young guys looking up to you and asking you questions about what to do here and what to do there. It’s absolutely great.”
Hugely likeable off the field but a true competitor on it, Williams will remain one of Wales’ most important players when he moves to Saracens. He hopes to join the European champions on a high.
“Munster have a really big pack and a couple of sharp backs, but as long as we get our own house in order we are really looking forward to the challenge,” said the fearless Scarlets back.
“I’m going to go out there on Saturday and give it my all and we’ll see where we are after the game.
“Hopefully I can end on a high.”
