Bernie's mother and father have flown to Glasgow for what is sure to be an emotional occasion for his family and the home support. Bernie admitted that his seven-year-old son Mateo is the most upset in the family at his decision to leave Scotland and return home.
Bernie told the Scotsman: "It is the right time for me to go home. I have had eight great years in European rugby and great times here at Glasgow, building my family with kids born here, and I want to be nearer my family, friends and the better weather also!
"I want to work on the farm with my father, enjoy the outside weather, but also keep playing with my local amateur club (Sociedad Sportiva] and do something in rugby, with all the things I have learned from here.
"I ride and I am going to be like the 'gaucho', you know; I'm going to be one of them, putting the cows altogether, the barbecues … you're all welcome too! Mateo is the most sad in the family, because he has a lot of friends at his school and playing rugby.
"He speaks 'Glasgow' now, which is so funny. My wife Tere and I have Trini and Esperanza, which means 'hope' in English, was born in Glasgow a year ago, and we want them to grow now in Argentina.
"We have loved Glasgow, such nice people here. When I was coming here Francisco Leonelli told me 'bring an umbrella', but yes it's wet but it's nice too.
"It is an emotional time for me and my family. I told my family this will probably be my last professional game and my mother came last week. I called my dad and said 'C'mon dad, you can leave the farm. A cow can look after itself for one week, eh?' So he's come and got here yesterday."
Glasgow coach Sean Lineen paid tribute to the player who has played more games than any other Warrior over his four seasons in Glasgow.
"I can't speak highly enough of the guy," said Sean, "his ability as a player from when he turned up with his socks round his ankles to his commitment to the team and his attitude, which has been brilliant.
"He's been a great player to work with and is up there with the best signings I've made in my time with Glasgow.
"The benefit he's brought to the youngsters at the club has been huge and it shows the value of having a good foreign signing. We would like another player like him, but it is important to get the right player, a player who can fit in. Bernie will be very hard to replace, in many ways."
Bernie is determined to finish his time in Glasgow with a big game against the Scarlets. He said: "I am so happy to have played for Glasgow for the last four years, a lot of games and I don't think I can ask for more from my body at 34. Glasgow opened the door for me and I gave everything, and have great friends from here who I will keep in touch with. I am not sad, just happy to have been in Glasgow, and now I want to finish well.
"This is a big game for me, but for the team and the supporters as well and we all want to finish well to give the supporters a thank-you for supporting us in a season where we haven't done so well."
