Sam Burgess will make the switch to rugby union in October and England fly-half Owen Farrell has backed him to succeed.
Burgess, 25, will move from South Sydney Rabbitohs at the end of the NRL season, making the big-money switch to Aviva Premiership side Bath.
"He is an unbelievable player. Rugby Union is very different but I am sure he can transfer what he did in League over to Union," Farrell told GiveMeSport in an interview at Wembley.
The 25-year-old played for Bradford Bulls during 2006-09 before moving to the Australian side. He has subsequently made 72 appearances for the Rabbitohs, scoring 17 tries.
He was also one of England's stars during the Rugby League World Cup in 2013, helping the hosts reach the last four before a heartbreaking defeat to New Zealand in the last four.
"I'm sure he will make a massive impact once he is settled," added the 22-year-old Saracens player.
Burgess, who was born in Yorkshire, has seen South Sydney struggle at the start of their new season Down Under, winning just one of their first three games.
However, he'll be hoping to lead his side to the NRL Grand Final and leave on high, with expectation already building ahead of his arrival at the Rec next season.
Owen Farrell, a BT Sport Ambassador, was speaking ahead of the Saracens-Harlequins clash at Wembley on Saturday, 22nd March. Watch the game live on BT Sport 1, with kick-off at 3:15pm.
