Sione Tuipulotu says “people will be very surprised” by his brother Mosese and believes he is just what Edinburgh need.
The 23-year-old Waratahs centre has signed a two-year deal to join Sean Everitt’s team this summer.
His older brother is excited to see what he will bring to the Scottish game.
“I won’t speak about his rugby because I know he’s going to come over and show it for himself,” Sione told the BBC Scotland Rugby Podcast.
“I will tell you about his personality. He’s the most competitive person that I’ve ever met and he plays with a chip on his shoulder.
“I’m looking forward to him coming over here and I know he’ll be using the motivation to prove a lot of people wrong. I’m excited for him to come over and do it.
“I know what type of person he is first and foremost; he’s competitive, and in sport in general I’ve had a lot of run-ins with him when we were younger in the backyard that often turned to blows.
“If there’s one thing I can say, it’s that Edinburgh are getting a very competitive player.
“I know what he’s going to bring to their side and to be honest I think he’s exactly what they need.”
