Leicester centre Tuilagi was born on Savai’i, the largest island in Samoa and is the youngest of six brothers, four of whom went on to represent their birth nation.
His brother Freddie was selected for Samoa at the 1991 World Cup – the year Manu was born.
Having moved to the United Kingdom to join his brothers, Tuilagi qualified for England through residency and was eventually named in the training squad for the 2011 World Cup, making his international debut against Wales where he scored a try.
Tuilagi became England’s youngest player to appear at a World Cup, aged 20 years and 115 days when he featured against Argentina, breaking the record set by Jonny Wilkinson.
As well as overcoming some serious injury setbacks, Tuilagi – who earned just two caps between 2014 and 2019 – has also been through several off-field issues.
He was fined £3,000 by England rugby officials after jumping from a ferry in Auckland during the 2011 World Cup and then missed out on selection for the home 2015 tournament after admitting he assaulted two female police officers following a night out in Leicester.
