Centre Scott Williams hopes to make the most of Jonathan Davies' misfortune when he fills in for his Scarlets team-mate in the Wales midfield against Argentina.
Williams starts at outside centre against the Pumas after Davies was ruled out by a groin injury. With Jamie Roberts returning to the number 12 jersey after missing the tour of Australia with a knee problem and Osprey Ashley Beck also in the national squad there is fierce competition for places.
And 22-year-old Williams hopes to lay claim for a role for the crunch fixtures against New Zealand and Australia with a strong display versus the Pumas. He said: "Obviously it is a bit unlucky for Jon but I need to take all the opportunities I can really."
Williams added: "We have got a few good centres, a lot of good competition and it can only be a good thing as it brings out the best in all of us in training and we are all trying to outdo each other.
"To be involved in all the games is one of my targets. Jon was a bit unlucky this weekend and I back myself to step in and do an equal job and hopefully I can take my opportunity."
Williams' centre partner Roberts will be under scrutiny after it was confirmed he will leave Cardiff Blues at the end of the season.
The British and Irish Lion is tipped to move to big-spending French club Racing Metro and join the likes of Mike Phillips, Gethin Jenkins and James Hook in plying his trade across the Channel. But Williams is relishing the chance to start alongside Roberts for the first time since last December's defeat to Australia in Cardiff.
"It is great to play with Jamie, we have trained well all week," he said. "I have played with him a few times and he gets over the gainline, so you have to make a good support line off him if he makes a break, and hopefully we will get a few of them and I can get on the end of a pass."
Williams will be forever remembered by Welsh fans for his solo try against England which saw Wales win the Triple Crown for the first time at Twickenham. But he is keen to ensure he does not end up being rugby's version of a one-hit wonder.
He said: "I feel I am learning every game and I am definitely not the finished product, I am trying to learn and get better and develop under the coaches. To try and get some form and continue to put good performances in, that is my top goal."
