Alesana Tuilagi was the man of the match in that game.
The Pacific Islanders are well known for their incredible physique and for their big hits on the rugby field. However, you will rarely see a nation like Samoa, Fiji or Tonga win against big teams like South Africa, New Zealand, or Australia. This is why the win of Samoa rugby against Australia in Sydney is absolutely unreal. Not only did they win, but they absolutely destroyed the Wallabies physically putting in some of the biggest hits you will see in a rugby highlight.
Alesana Tuilagi played an essential role in this match, the genetic freak absolutely dominated his opponents and score a crazy counterattack try.
