"This is an excellent capture for Sale Sharks. Tasesa is a quality act and he will fit in perfectly with our plans for next season," said executive director of sport Steve Diamond.
Commenting on his move Tasesa said, "Having played a lot of top level rugby in the Southern Hemisphere and in the past 2 years experiencing success in the Top 14 with Clermont, it is a fantastic opportunity for me to experience another tough, world class competition with Sale Sharks. I like the fact that the club is making changes and want a fresh start and it is exactly the type of challenge I am looking for."
