The additions of Anthony Watson and Jimmy Gopperth headline a raft of new signings and re-signings at Leicester ahead of next season.
The addition of Watson from Bath, a move long-rumoured, is seen as a real coup, while Gopperth, evergreen at 39 in June, said the move would enrich his rugby career.
“Anthony is a world-class player who has played at the highest levels of the game over a number of seasons,” said Leicester head coach Steve Borthwick.
“While he has reached great heights, he is incredibly keen to develop his game, remains ambitious and has a lot more he wants to achieve.
“Jimmy has shown for a number of years in some of the world’s most competitive and tough environments that he is a world-class player.
“A prolific points-scorer capable of playing in various positions, he not only adds valuable depth to our squad but an incredible amount of experience and knowledge.
“Jimmy is a proven leader and someone who makes the players around him better.”
On top of those two, Leicester also re-signed vastly experienced duo Chris Ashton and Richard Wigglesworth, as well as snapping up Biarritz and former Munster prop James Cronin, London Irish flanker Olly Cracknell and outside back Phil Cokanasiga.
There are also contract extensions for Sean Jansen, Kiri Murimurivalu and Harry Simmons.
