South Africa and Saracens prop Vincent Koch will join Wasps next season, the club announced on Thursday.
The 31-year-old, who has 31 international caps and played a crucial part in the Springboks side that lifted the 2019 Rugby World Cup in Japan, has played his club rugby in England since joining Saracens in 2016.
“The saying goes ‘a change is as good as a holiday,'” Koch said in a statement. “Saracens have been amazing over the last couple of years, and I have had great times there, that I will always treasure.
“But I believe it’s time for a change, and a new challenge at Wasps is what I need for the next chapter of my career.”
Koch made over 100 appearances for Saracens, winning the European Champions Cup in 2017, as well as two Premiership titles.
Wasps head coach Lee Blackett said: “We have been looking for a world-class tighthead-prop and in Vincent we have found our man.
“We are thrilled to be able to bring an experienced international forward like him on board for next season. He will really add to our scrum and our environment next season, having been a proven winner at club and international levels for many years now.”
