With England set to face Argentina on Saturday in a crucial Rugby World Cup Pool C clash, we take a look at some of the best players to have won the European Cup from the South American nation. 

Juan Martin Fernandez Lobbe 

Fernandez Lobbe was a three-time European Cup winner who enjoyed an outstanding career for club and country, featuring 55 times in European rugby, as well as making 71 appearances for the Pumas. 

He spent the first three seasons of his European career with Sale Sharks, helping them reach the semi-finals of the Challenge Cup in 2008, before falling to a 36-14 defeat against eventual winners Bath Rugby. 

The back-row forward then moved to RC Toulon, where he had tremendous success in Europe as the French side collected three consecutive European Cups between 2013 and 2015, beating ASM Clermont Auvergne twice in between a 23-6 final victory over Saracens. 

Marcello Bosch 

Centre Bosch was a double Champions Cup winner and also landed a Challenge Cup winners’ medal in a European career comprising 63 appearances and 73 points.  

He first featured for Biarritz from 2006 to 2013, winning the Challenge Cup in 2012 via a 21-18 win over RC Toulon at Twickenham Stoop. 

Bosch had even greater success after moving to Saracens, coming off the replacements bench in their 21-9 2016 Champions Cup final win over Racing 92 and playing the full 80 minutes when the English club saw off ASM Clermont Auvergne 28-17 at BT Murrayfield in 2017. 

Juan Martin Hernandez 

The 74-cap Pumas utility back starred in Europe for a trio of French clubs, playing in the European Cup for Stade Francais Paris, Racing 92 and RC Toulon. 

Hernandez notched 113 points in 45 European appearances, with his most notable being his sole outing for Toulon in their 24-18 final victory over ASM Clermont Auvergne at Twickenham in 2015. 

Juan Figallo 

The 31-year-old prop started his European career with Montpellier, but it is with Saracens where he has had most success. 

In a stop-start European rugby career, Figallo played seven times in four seasons for the French side, before moving to Saracens in 2014 and he has gone on to play his part in their Champions Cup-winning squads of 2016, 2017 and 2019, although he only played in the 2016 final.
