Zebre suffered their second biggest Guinness PRO12 defeat on their visit to Leinster on Friday and have only ever beaten an Irish province once before 13-6 when Ulster visited Parma in September 2014.
Connacht have the best attack in the Guinness PRO12 having scored 36 tries in their campaign so far. The Irishmen have won their last three matches in all competitions and have also won on their last four visits to Italy.
The two sides have met on eleven previous occasions in all tournaments with Connacht winning them all, the most recent four with a try bonus, whilst Zebre have secured just two losing bonus points – both in 2013.
