As England and Wales prepare to go head-to-head in the Old Mutual Wealth Cup on Sunday, we look at some of the key battles that will go a long way to deciding who will win bragging rights at Twickenham, live on Sky Sports 3. Courtney Lawes v Alun Wyn Jones Wales are boosted by the return to fitness of Alun Wyn Jones The second rows contain two men with a point to prove.Alun Wyn Jones returns to the scene of his last appearance before suffering a foot injury. He will be raring to get back into action, especially against the old enemy and it will be an invaluable opportunity to blow off the cobwebs, find some match fitness and test the foot that has plagued him for so long. Jones has been hitting the headlines since his return to the Wales camp, his team-mates championing his presence in training, setting the standards of how things should be done. He is the kind of talismanic figure his side will need to take on the All Blacks and will provide a huge boost ahead of the Twickenham clash. Courtney Lawes (right) will look to force his way back into England reckoning with a strong performance against Wales Another man keen to impress will be his opposite number, Courtney Lawes.The Northampton man was a key figure during the Stuart Lancaster era but has found himself on the outskirts of Eddie Jones plans since the emergence of Saracens duo George Kruis and Maro Itoje paired with the club form of Joe Launchbury. Jones will be looking to the 45-cap international to come to the fore and showcase his trademark physicality while setting the example to the younger forwards around him.However, there is more to Lawes game than just bone-crunching tackles and his athleticism and deceptive turn of pace could prove vital if he is to get the upper hand on the class operator of Jones.Jack Clifford v Taulupe Faletau Jack Clifford gets a chance to shine in the No 8 shirt in the absence of Billy Vunipola The battle of the No 8s is not one for the faint-hearted as an experienced operator takes on a young gun keen to impress.A stand-out performer every time he pulls on the Welsh jersey, Faletau is a key figure in Warren Gatlands pack. The Bath-bound forward was a model of consistency throughout the World Cup and Six Nations, receiving the accolade of the Welsh Rugby Writers player of the season for his performances.Faletau is a strong ball carrier who will provide Wales the go-forward they need to unleash a dangerous looking backline. Despite his fierce approach to the game, he is ever-present in the Welsh line-up and since the first of his 57 caps against the Barbarians back in June 2011, the 25-year-old has racked up an impressive 4,280 minutes of rugby, putting in 596 carries. The ever present Taulupe Faletau will prove vital to Wales chances against England The man who faces the task of silencing the Faletau is Jack Clifford. The Harlequin has big shoes to fill with Billy Vunipola otherwise engaged with club duties, however the versatile back row had a breakthrough season in the Aviva Premiership, leading to five caps from the bench as England secured the Grand Slam.However, dont be fooled into thinking that Clifford is just there to keep the shirt warm for Vunipola. He has been a key cog in the Harlequins machine that reached the Challenge Cup final, providing a turn of pace and relentless work rate in a young and exciting pack.Ben Youngs v Rhys Webb Rhys Webb has looked sharp for the Ospreys since his return from a long-term foot injury After a difficult World Cup campaign, Ben Youngs came out firing and featured in all of Englands Six Nations matches. The scrum-half found himself on the bench for the decider in Paris, making a telling impact in the closing minutes.In club colours, Youngs has returned to his orchestrating best, pulling the strings as Leicester made both European and domestic semi-finals.The eye-catching form of his rival Danny Care will be sure to keep the 2013 British and Irish Lions representative on his toes and he will be key in gelling a team of seasoned internationals and uncapped newcomers.Youngs will come up against livewire Rhys Webb. The Ospreys scrum-half has looked sharp since his comeback from the foot injury that forced him out of the World Cup and regained the Welsh No 9 shirt for their final Six Nations game against Italy. Ben Youngs faces tough competition at scrum-half Despite making just 18 appearances for Wales since his debut against Italy in 2012, Webb has racked up six tries and will be hoping his heads-up style of rugby paired with his composure in the middle will conjure up some magic for Warren Gatlands men.Webb will be fresh and raring to go ahead of his countrys summer tour to take on world champions New Zealand and will be keen to put a marker down in the hotly-contested scrum-half battle.Luther Burrell v Jamie Roberts Luther Burrell says he is over missing the World Cup and is only focused on the upcoming games against Wales and Australia It could be argued that bar Stuart Lancaster, Luther Burrell was the biggest casualty of the Sam Burgess experiment, missing out on a place in the World Cup squad at the expense of the rugby league convert.The Northampton centre will have a big point to prove when he lines up at inside centre against Wales.A dip in form after his World Cup omission has seen Burrell dragged into a battle with young club mate Harry Mallinder for the Northampton centre berth. However, it seems to have been the push the 28-year-old needed, reigniting the passion that had made him one of Englands first choice centres sparking a return to form for the former rugby league man. With Farrell and Slade unavailable due to club commitments and Manu Tuilagi facing a spell on the sidelines with a hamstring injury, now is Burrells time to stake his claim for the England inside centre spot. Jamie Roberts provides Wales with solidity in both attack and defence However, to impress against Wales he will have to withstand the force that is Jamie Roberts. The Harlequins man is a world-class operator who has chalked up 76 caps for his country and played a decisive role as the Lions took a series victory in Australia in 2013.Roberts, at 6ft 4in and almost 18 stone, provides a rock-solid defensive obstacle as well as the ability to provide a game-making score. In the Six Nations win against Scotland, he put in nine tackles in defence, more than his back three combined, before securing the victory for Wales when he burst over from close range.He is the cement that holds Gatlands backline together and his impact will go a long way to deciding the outcome between the two sides.Watch England v Wales live on Sky Sports 3 HD on Sunday from 2.30pm.

Brisbane Lions great Jonathan Brown is certain Justin Leppitsch will see out the season as coach of the struggling AFL club, even if they lose a likely wooden spoon decider against Essendon.Leigh Matthews is a sticker and they wont do the same as what they did to Michael Voss that was sacked with three games to go in 2013, Brown said on radio station Nova 100.But whether his three-time former premiership teammate will be in charge in 2017 is another matter.That will be up to the board, Brown said.Any time they are doing board reviews and the AFL is getting involved, you cannot guarantee the coach going forward.Leppitsch, who is contracted to the end of next season, is keeping a stoic front as pressure continues to mount on his shoulders.The Lions have won just 12 out of 60 games under his coaching, with home crowds at record lows and their current losing streak the worst in club history.But Leppitsch says they expect to beat the suspension-ravaged Bombers, the AFLs only other one-win team in 22016, even if he was careful to play down the significance of what that might mean.ddddddddddddrobably externally it does take the heat off for a week, he told reporters.We know what our planning is based on and where its going. Its been harder for the public to accept it more than the team itself ... externally its been harder to sell the message.I understand that, for some reason, when the facts are sort of there that we are a young team.Leppitsch also denied Saturdays match will decide who finishes last, pointing to Brisbanes final-round win over the Western Bulldogs last year which saw the spoon fall to Carlton.Last year we were in this position in the last game of the year and somehow didnt get the wooden spoon, he said.Everyone basically gifted it to us, it was in the mail on the way to the Gabba and we beat a finalist in the last week not to get it, he said.
