Sale lock Kearnan Lyall is to join Wasps at the end of the season.
The England Saxons second row will move south in the summer to join a formidable pack which will still include Marco Wentzel, who has signed a new contract with the London club.
Wasps announced the double deal in a statement on their website which said Lyall and Wentzel are "currently the top two lineout ball winners in the Aviva Premiership, according to Opta statistics".
Director of rugby Dai Young welcomed the news, saying: "Marco has been a huge performer for us over the past two seasons.
"He continues to be a real leader for us at the lineout and it's great to have him on board next season again.
"Kearnan is someone who has been an ever-present for Sale and someone who has really impressed us.
"I believe he is a player who has the potential to go further in his career and earn greater international recognition.
"Second row is a real physical position and there's a long season there, so making sure we had a very strong mix in this area was important to us and we've got that now."
Wasps' other second row options include James Cannon and England internationals Joe Launchbury and Tom Palmer.
