Fourie originally moved to the United Kingdom to play for Rotherham
Leeds Carnegie's Hendre Fourie has described his selection for England as a "fairytale."
The openside flanker will make his international debut when he starts against the Australian Barbarians on Tuesday in Perth.
The 30-year-old told the RFU.com podcast: "It's a fairytale and has happened so quickly.
"It comes off a great season at Leeds for both the club and me and hopefully I can take that form into this match."
South African-born Fourie qualifies for England through residency and will make his full international debut after an impressive season at Leeds, which saw him named both the players' and supporters' player of the season.
"After what we achieved at Leeds this season I am very confident and want to take that momentum into this tour," he said.
"When I first moved to England I never thought about playing for England, but it just came on leaps and bounds from last September and now it's here I need to take my chance with both hands.
"I don't think the step up from club rugby to international rugby is as big as people think it is.
"That's because of the quality of the Premiership and the quality of the players in the league as there are so many top quality internationals that play in the Premiership.
"Of course it is a step up and I just have to keep my head and do what I normally do. If I give an extra 10% then hopefully I should be alright."
