Argentina inside centre Juan Martín Hernández admits he cannot wait to face off against Australia's Matt Giteau in their World Cup semi-final.
Sunday will see the former Toulon team-mates collide and both have been complimentary of each other in the lead-up to the Twickenham fixture.
Together the skillful duo were part of a successful Toulon side and there's sure to be a great deal of on-field respect between the pair this weekend.
"I am looking forward to playing against him. It is a big challenge to play against one of the best players that rugby has ever had. His skills are amazing. It is going to be different in the centres to the game against Ireland (in the quarter-finals)," said the Pumas playmaking centre.
Hernández will be boosted by the return from suspension of midfield team-mate Marcelo Bosch, who he believes will have a big impact on Sunday.
"Marcelo is a great defender. He leads our backline defence and he has a lot of experience. Australia have some big ball carriers. Marcelo is important because he makes the last decision," he said before stressing that he was not shocked that his side had made the final four.
"I am not surprised because we have worked a lot for this. It has cost me a lot to get here. We are happy to have made it but we are here to win," he said.
