The captain Quintin Geldenhuys and Carlo Del Fava, who spent two years playing for Ulster and skippered the side for part of the 2008-2009 season before moving in Viadana, are the locks; Erasmus and Krause are named as the flankers with Williams at No.8
However there are several changes on the bench, where Italian internationals Josh Sole and Pablo Canavosio made their first appearances of the season after recovering from injury, while hooker Luigi Ferraro and prop Luca Redolfini also find places on the bench.
