George Ford has been working with Jonny Wilkinson to turn the drop-goal into a weapon at the World Cup.

Ford landed three as England opened the tournament with a 27-10 rout of Argentina in Marseille last Saturday and is ready to continue using them if the opportunity arises.

To assist with the tactic, the Sale fly-half has been perfecting his technique with Wilkinson, who famously landed the drop-goal that enabled England to lift the World Cup in 2003.

“Jonny’s big thing is don’t worry about the posts,” said Ford, who continues in the number 10 jersey for Sunday’s showdown with Japan in Nice.

“Obviously you need to know where they are, but the only thing you can control is what you do in terms of how you place the ball and what you do with your body.

“Jonny said you can have the ugliest drop in the world but if you get your body right and the ball is in the slot, and you get the momentum of your body towards the target, you can do it.

“How many drop goals do you see that flap over? A lot of kickers say if you speak to kids growing up they are constantly looking at the posts as if they are going move to make the ball go over.

“The drop-goal has probably been underused. You watch Jonny’s era in 2003 and 2007 and the influence drop-goals had on the game then was enormous.

“Maybe the game has tipped the balance the other side of the spectrum where everyone thinks you need to score tries every two minutes, but you need a variety of ways of scoring.

“We had spoken quite a bit about them in pre-season and how big they can be, especially at World Cups. They can be really effective and hopefully we can show that again.”

In training, Ford competes with fellow playmakers Owen Farrell and Marcus Smith to see how many drop-goals they can kick – under the watchful eye of rugby league great Kevin Sinfield, who is now England’s defence coach.

“It is interesting speaking to Kev because in rugby league you might not see as many drop-goals because it is only worth one point,” Ford said.

“But he said as soon as play-off games came around, how much they practised went through the roof because they knew they would need a couple in a semi or a final, so we are doing this thing at the minute where we kick until we miss.

“Obviously if you don’t kick many before you miss you might go again, but there is a fair bit of competition and pressure between myself, Owen and Marcus when we are doing it.

“We are bringing lads over to come and put pressure on us, because we are not daft, you are not in armchair. You need to make it as realistic as possible.”

Kyle Sinckler was inspired to play for England by the 2003 World Cup final – despite being forced to miss Jonny Wilkinson’s drop-goal in order to study maths.

Sinckler was 10 years old when he watched on television as Martin Johnson’s side were held 14-14 by Australia at the end of 80 minutes, ushering in a period of extra time that was ultimately settled by Wilkinson’s boot.

But the enthralled Sinckler never got to see the greatest moment in English rugby history as his mum Donna had ordered him to study.

“Watching 2003 was a massive motivator for me. I remember when the final was on, I had a maths tutor,” the Bristol prop said.

“Obviously it went to extra time and then my mum – honestly I don’t know, she’s so ruthless that woman sometimes – she literally turned the TV off and took me to my maths tutor.

“So I had to do my maths lesson and I found out afterwards that we’d won! Honestly, it was full-time and she said ‘you’re going to your maths tutor’. I said: ‘You’re joking!’

“But she was adamant: ‘Nope. I’m paying my money. I’m working hard to pay for your maths tutor so you’re going.’

“I was like: ‘You are so evil, ridiculous!’ Don’t even start with that woman! Nuts. Nuts!

“Before that I was literally glued to the TV, it was so inspiring for me watching that. It gave me, I guess, the hope that I wanted to emulate that one day.”

England are desperately short of form for their latest attempt to claim a second world title having lost five of their last six Tests.

They open France 2023 with a tricky clash against Argentina, who sit two places higher in the global rankings in sixth.

“It’s the real deal straight away. Every Test match you play it’s tough. I’ve never had an easy Test match in my life,” said Sinckler, who is expected to overcome a chest injury in time to face the Pumas.

“It pushes you to the limit and that’s why it’s called a Test – it does test you. But if you want to be the best, you’ve got to beat the best.”
