The Ospreys will be hoping 13 is their lucky number as they look to exact revenge against Biarritz Olympique in their Pool opener at the Liberty Stadium on Saturday.
The Welsh region have won their last 12 home games in Europe since 2007 and are determined to make it 13 when they face a Biarritz side which beat them 29-28 in a dramatic semi-final in San Sebastien in 2010.
But the Basque outfit, who reached the final of the European Cup final in 2006 and 2010, will have targeted lifting a trophy which they have come so close to winning but never have.
The Ospreys, who failed to reach the quarterfinals of the tournament for the first time in four years last season, will want to restore their reputation in Europe and become the first side to lift the European Cup.
Ospreys: 15 Richard Fussell, 14 Tommy Bowe, 13 Andrew Bishop, 12 Ashley Beck, 11 Shane Williams, 10 Dan Biggar, 9 Kahn Fotuali'i, 8 Jonathan Thomas, 7 Justin Tipuric, 6 George Stowers, 5 Ian Evans, 4 Alun Wyn Jones (captain), 3 Adam Jones, 2 Huw Bennett, 1 Duncan Jones.
Replacements: 16 Richard Hibbard, 17 Ryan Bevington, 18 Aaron Jarvis, 19 Ryan Jones, 20 Joe Bearman, 21 Rhys Webb, 22 Matthew Morgan, 23 Sonny Parker.
Biarritz: 15 Dane Haylett-Petty, 14 Taku Ngwenya, 13 Marcelo Bosch, 12 Damien Traille, 11 Iain Balshaw, 10 Julien Peyrelongue, 9 Dimitri Yachvili, 8 Raphael Lakafia, 7 Imanol Harinordoquy, 6 Benoit Guyot, 5 Erik Lund, 4 Jérôme Thion, 3 Sylvain Marconnet, 2 Benoit August, 1 Fabien Barcella.
Replacements: 16 Arnaud Heguy, 17 Yvan Watremez, 18 Francisco Gomez Kodela, 19 Pelu Taele, 20 Florian Faure, 21 Romain Terrain, 22 Benoît Baby, 23 Ilikena Bolakoro.
