Josh Matavesi has left Exeter Chiefs after accepting an offer to join Top 14 outfit Racing Metro.
The 20-year-old has initially agree to move to Paris as a 'medical joker' following an injury to Juan Martin Hernandez.
However the Fiji international, who came through the academy ranks at the Chiefs, will then take up the offer of a two-year deal from the start of next season.
And although Matavesi admits it will be hard to leave Sandy Park, he believes he needs more game time if he is to continue his development.
"Whilst I am looking forward to the new challenge, it's been an emotional day for me," Matavesi told the club's official site.
"For the past two years I have spent nearly every day with the guys and built some good relationships with everyone at the club.
"At somewhere like Exeter you don't have just one best friend within the squad, your friends are the whole squad because we are such a tight-knit bunch.
"If I'm honest I don't really want to go because of the boys and that, but I need to play rugby if I want to improve.
"Opportunities like this don't come along very often. I've just turned 20 and playing in the Top 14 with a club like Racing Metro is definitely something special.
"However, I just have to really concentrate for the initial few weeks; get my head down and settle in as best I can."
