Dan Carter has warned England to beware of "freak" Nemani Nadolo when Fiji head to Twickenham for Friday's World Cup opener.
The New Zealand fly-half has spent the past two seasons playing alongside Nadolo at the Crusaders, witnessing first hand the havoc caused by the 20-stone, 6ft 5in giant who was the top try-scorer in Super Rugby in 2014.
"Nadolo is bit of a freak. He's a huge man, but is also very skilful. He's a quality player and one to watch," said Carter..
"He's a proud Fijian and will be a real threat at this World Cup, not just against England, but against all the teams who Fiji face.
"Nadolo has this funny Australian accent which you wouldn't really expect from a Fijian.
"He's an absolute top bloke, very genuine and down to earth. He's typical Fijian - a relaxed character who enjoys himself and doesn't take life too seriously.
"Fiji could potentially cause an upset because they're a strong side."
