Krause will end his career playing for Aironi against Ospreys on Friday 6th May in the last regular match of the Magners League season.
"I want to thank all the fans for their support and all the people involved in the rugby organisation for the help I received in all those years. I wish them all the best for the future".
Aironi's Director of Rugby Franco Tonni: "In Viadana Gareth confirmed to be a great player and a great guy. Probably he is one of the best foreigner players arrived to Italy in the last five years. The door will stay open for Gareth: if rules change or if Aironi will need help during the season, he could be back in Viadana. Meanwhile, we just can thank him for his behavior on and off the pitch".
