Title clash between Wales and England will include extreme sledging - Williams

"A lot of these lads will have played together, but that won't matter in Cardiff," said Williams, who is taking part in the LMAX Exchange Everest Rugby Challenge on behalf of Wooden Spoon.

"They'll know all their little secrets from their time together with the Lions, the nitty gritty.

"I can assure you that for however long that game goes on, Alun Wyn Jones won't shut up. I can vouch for that. Kyle Sinckler likes to talk as well. Owen Farrell doesn't shut up either.

"The banter is going to be extreme, it really is. It's about trying to put off your opposition.

"A nice little late hit on Owen Farrell a couple of times to try and put him off, as we saw Ross Moriarty do a couple of seasons ago. That didn't work!

"If you can make Owen Farrell miss a couple of kicks, then you've done your job.

"Or if you can pit Alun Wyn Jones off his game, or shut up the likes of Sinckler, then you're doing your job. That's the nature of the beast.

"It's not all physical out there – you have to be mentally tough and be able to take stick. They'll say anything they can to put you off.

"If you retaliate then it's a yellow or a red card. Thank you very much – I'll have that all day long. I'll take one on the chin for that.

"That's what rugby is and I've experienced it, especially in these big games. But they'll say whatever they want on the field, but as soon as the whistle goes they'll shake hands – and that's rugby."

Three games into his Test career, Williams was given a brutal taste of how effective a taunting opponent can be.

Wales were thrashed 46-12 by England in his debut Six Nations campaign and Williams was unable to ignore the taunts made by opposite number Austin Healey.

"One of my first games was at Twickenham and we got absolutely pummelled," Williams said.

"I was playing against Austin Healey, who didn't shut up for 80 minutes. I remember thinking 'no wonder my family don't like the English if this guy is anything to go by'.

"He completely put me off my game. He absolutely mentally broke me. He really did.

"He was telling me 'come on Williams, I thought you had gas. You're much slower than I thought you'd be'.

"By the end, I was looking at the touchline thinking 'I've had enough now, he's absolutely broken me'. He's like that – he's still chopsy. But it's banter and that's how it goes."
